Solving Captchas

Our API is based on HTTP requests and supports both HTTP and HTTPS protocols.

API endpoints:

  • http://2captcha.com/in.php is used to submit a captcha
  • http://2captcha.com/res.php is used to get the captcha solution

The process of solving captchas with 2captcha is really easy and it's mostly the same for all types of captchas:

  1. Get your API key from your account settings page. Each user is given a unique authentication token, we call it API key. It's a 32-characters string that looks like:
    1abc234de56fab7c89012d34e56fa7b8
    This key will be used for all your requests to our server.
  2. Submit a HTTP POST request to our API URL: http://2captcha.com/in.php with parameters corresponding to the type of your captcha.
    Server will return captcha ID or an error code if something went wrong.
  3. Make a timeout: 20 seconds for reCAPTCHA, 5 seconds for other types of captchas.
  4. Submit a HTTP GET request to our API URL: http://2captcha.com/res.php to get the result.
    If captcha is already solved server will return the answer in format corresponding to the type of your captcha.
    By default answers are returned as plain text like: OK|Your answer. But answer can also be returned as JSON {"status":1,"request":"TEXT"} if json parameter is used.
    If captcha is not solved yet server will return CAPCHA_NOT_READY result. Repeat your request in 5 seconds.
    If something went wrong server will return an error code.

Normal Captcha

Normal Captcha is an image that contains distored but human-readable text. To solve the captcha user have to type the text from the image.

To solve the captcha with our service you have to submit the image with HTTP POST request to our API URL: http://2captcha.com/in.php
Server accepts images in multipart or base64 format.

Multipart sample form

<form method="post" action="http://2captcha.com/in.php" enctype="multipart/form-data">
<input type="hidden" name="method" value="post">
Your key:
<input type="text" name="key" value="YOUR_APIKEY">
The CAPTCHA file:
<input type="file" name="file">
<input type="submit" value="Upload and get the ID">
</form>

YOUR_APIKEY is Your API key.

Base64 sample form

<form method="post" action="http://2captcha.com/in.php">
<input type="hidden" name="method" value="base64">
Your key:
<input type="text" name="key" value="YOUR_APIKEY">
The CAPTCHA file body in base64 format:
<textarea name="body">BASE64_FILE</textarea>
<input type="submit" value="Upload and get the ID">
</form>

YOUR_APIKEY is your API key.

BASE64_FILE is base64-encoded image body.

You can provide additional parameters with your request to define what kind of captcha you're sending and to help workers to solve your captcha correctly. You can find the full list of parameters in the table below.

If everything is fine server will return the ID of your captcha as plain text, like: OK|2122988149 or as JSON {"status":1,"request":"2122988149"} if json parameter was used.

If something went wrong server will return an error. See Error Handling chapter for the list of errors.

Make a 5 seconds timeout and submit a HTTP GET request to our API URL: http://2captcha.com/res.php providing the captcha ID. The list of parameters is in the table below.

If everything is fine and your captcha is solved server will return the answer as plain text, like: OK|TEXT or as JSON {"status":1,"request":"TEXT"} if json parameter was used.

Otherwise server will return CAPCHA_NOT_READY that means that your captcha is not solved yet. Just repeat your request in 5 seconds.

If something went wrong server will return an error. See Error Handling chapter for the list of errors.

reCAPTCHA V2

reCAPTCHA V2 also known as I'm not a robot reCAPTCHA is a very popular type of captcha that looks like this:

Solving reCAPTCHA V2 with our new method is pretty simple:

  1. Look at the element's code at the page where you found reCAPTCHA.

  2. Find a link that begins with www.google.com/recaptcha/api2/anchor or find data-sitekey parameter.

  3. Copy the value of k parameter of the link (or value of data-sitekey parameter).

  4. Submit a HTTP GET or POST request to our API URL: http://2captcha.com/in.php with method set to userrecaptcha and provide the value found on previous step as value for googlekey and full page URL as value for pageurl. Sending proxies is not obligatory ar the moment but it's recommended.
    You can find the full list of parameters in the table below.

    Request URL example:

    http://2captcha.com/in.php?key=1abc234de56fab7c89012d34e56fa7b8&method=userrecaptcha&googlekey=6Le-wvkSVVABCPBMRTvw0Q4Muexq1bi0DJwx_mJ-&pageurl=http://mysite.com/page/with/recaptcha
  5. If everything is fine server will return the ID of your captcha as plain text, like: OK|2122988149 or as JSON {"status":1,"request":"2122988149"} if json parameter was used.
    Otherwise server will return an error code.

  6. Make a 15-20 seconds timeout then submit a HTTP GET request to our API URL: http://2captcha.com/res.php to get the result.
    The full list of parameters is in the table below.

    If captcha is already solved server will respond in plain text or JSON and return the answer token that looks like:

    03AHJ_Vuve5Asa4koK3KSMyUkCq0vUFCR5Im4CwB7PzO3dCxIo11i53epEraq-uBO5mVm2XRikL8iKOWr0aG50sCuej9bXx5qcviUGSm4iK4NC_Q88flavWhaTXSh0VxoihBwBjXxwXuJZ-WGN5Sy4dtUl2wbpMqAj8Zwup1vyCaQJWFvRjYGWJ_TQBKTXNB5CCOgncqLetmJ6B6Cos7qoQyaB8ZzBOTGf5KSP6e-K9niYs772f53Oof6aJeSUDNjiKG9gN3FTrdwKwdnAwEYX-F37sI_vLB1Zs8NQo0PObHYy0b0sf7WSLkzzcIgW9GR0FwcCCm1P8lB-50GQHPEBJUHNnhJyDzwRoRAkVzrf7UkV8wKCdTwrrWqiYDgbrzURfHc2ESsp020MicJTasSiXmNRgryt-gf50q5BMkiRH7osm4DoUgsjc_XyQiEmQmxl5sqZP7aKsaE-EM00x59XsPzD3m3YI6SRCFRUevSyumBd7KmXE8VuzIO9lgnnbka4-eZynZa6vbB9cO3QjLH0xSG3-egcplD1uLGh79wC34RF49Ui3eHwua4S9XHpH6YBe7gXzz6_mv-o-fxrOuphwfrtwvvi2FGfpTexWvxhqWICMFTTjFBCEGEgj7_IFWEKirXW2RTZCVF0Gid7EtIsoEeZkPbrcUISGmgtiJkJ_KojuKwImF0G0CsTlxYTOU2sPsd5o1JDt65wGniQR2IZufnPbbK76Yh_KI2DY4cUxMfcb2fAXcFMc9dcpHg6f9wBXhUtFYTu6pi5LhhGuhpkiGcv6vWYNxMrpWJW_pV7q8mPilwkAP-zw5MJxkgijl2wDMpM-UUQ_k37FVtf-ndbQAIPG7S469doZMmb5IZYgvcB4ojqCW3Vz6Q

    If captcha is not solved yet server will return CAPCHA_NOT_READY result. Repeat your request in 5 seconds.

    If something went wrong server will return an error code.

  7. Locate the element with id g-recaptcha-response and make it visible deleting display:none parameter.

    Please note: sometimes content on the page is generated dynamically and you will not see this element in html source.
    In such cases you have to explore javascript code that generates the content. "Inspect" option in Google Chrome can help in that.

    As an alternative you can just use javascript to set the value of g-recaptcha-response field:

    document.getElementById("g-recaptcha-response").innerHTML="TOKEN_FROM_2CAPTCHA";

  8. An input field will appear on the page. And you just have to paste the answer token to that field and submit the form.

  9. Congratulations, you've passed the recaptcha

reCAPTCHA Callback

Sometimes there's no submit button and a callback function is used isntead. The function is executed when reCAPTCHA is solved.

Callback function is usually defined in data-callback parameter of reCAPTCHA, for example:

data-callback="myCallbackFunction"

Or sometimes it's defined as callback parameter of grecaptcha.render function, for example:

grecaptcha.render('example', {
  'sitekey' : 'someSitekey',
  'callback' : myCallbackFunction,
  'theme' : 'dark'
});

Also there's another way to find the callback function - open javascript console of your browser and explore reCAPTCHA configuration object:

___grecaptcha_cfg.clients[0].aa.l.callback

Note that aa.l may change and there can be multiple clients so you have to check clients[1], clients[2] too.

Or just use the script that finds reCAPTCHA parameters

Finally all you have to do is to call that function:

myCallbackFunction();

Or even this way:

___grecaptcha_cfg.clients[0].aa.l.callback();

Sometimes it is required to provide an argument and in most cases you should put the token there. For example:

myCallbackFunction('TOKEN');

Invisible reCAPTCHA V2

reCAPTCHA V2 also has an invisible version.
You may check how it looks like here: https://www.google.com/recaptcha/api2/demo?invisible=true
Recently we noticed some changes in invisible reCAPTCHA algorithms on few websites and added new parameter invisible=1 that should be used for invisible reCAPTCHA.
Read more about invisible reCAPTCHA below.

Invisible reCAPTCHA is located on a DIV layer positioned -10 000 px from top that makes it invisible for user.

reCAPTCHA is activated on page load or on user's actions like click somewhere or submit a form - that depends on the website. If user's cookies are good enough then he will just pass it automatically and no additional actions will be required. Otherwise user will see standard reCAPTCHA form with a challenge.

In most cases when challenge is completed a callback function is executed. You can read more about callback here.

If you are still not sure — there are few ways to determine that reCAPTCHA is in invisible mode:

  • You don't see "I'm not a robot" checkbox on the page but getting recaptcha challenge when making some actions there
  • reCAPTCHA's iframe link contains parameter size=invisible
  • reCAPTCHA's configuration object contains parameter size that is set to invisible, for example ___grecaptcha_cfg.clients[0].aa.l.size is equal to invisible

How to bypass invisible reCAPTCHA in browser?


Method 1: using javascript:

  1. Change the value of g-recaptcha-response element to the token you received from our server:
  2. document.getElementById("g-recaptcha-response").innerHTML="TOKEN_FROM_2CAPTCHA";
    
  3. Execute the action that needs to be performed on the page after solving reCAPTCHA.

  4. Usually there's a form that should be submitted and you need to identify the form by id or name or any other attribute and then submit the form. Here are few examples:

    document.getElementById("recaptcha-demo-form").submit(); //by id "recaptcha-demo-form"
    document.getElementsByName("myFormName")[0].submit(); //by element name "myFormName"
    document.getElementsByClassName("example").submit(); //by class name "example"
    

    Or sometimes there's a callback function executed when reCAPTCHA is solved.

    Callback function is usually defined in data-callback parameter of reCAPTCHA, for example:

    data-callback="myCallbackFunction"

    Or sometimes it's defined as callback parameter of grecaptcha.render function, for example:

    grecaptcha.render('example', {
      'sitekey' : 'someSitekey',
      'callback' : myCallbackFunction,
      'theme' : 'dark'
    });

    And all you have to do is to call that function:

    myCallbackFunction();
  5. Voila! You've done that with just 2 strings of code.

Method 2: changing HTML:

  1. Cut the div containing reCAPTCHA from page body.
  2. <div style="visibility: hidden; position: absolute; width:100%; top: -10000px; left: 0px; right: 0px; transition: visibility 0s linear 0.3s, opacity 0.3s linear; opacity: 0;">
    <div style="width: 100%; height: 100%; position: fixed; top: 0px; left: 0px; z-index: 2000000000; background-color: #fff; opacity: 0.5;  filter: alpha(opacity=50)">
    </div>
    <div style="margin: 0 auto; top: 0px; left: 0px; right: 0px; position: absolute; border: 1px solid #ccc; z-index: 2000000000; background-color: #fff; overflow: hidden;">
    <iframe src="https://www.google.com/recaptcha/api2/bframe?hl=en&amp;v=r20170213115309&amp;k=6LfP0CITAAAAAHq9FOgCo7v_fb0-pmmH9VW3ziFs#zglq3yifgkmj" title="recaptcha challenge" style="width: 100%; height: 100%;" scrolling="no" name="zglq3yifgkmj" frameborder="0"></iframe>
    </div>
    </div>
    
  3. Cut the whole block:
  4. <div class=""><!-- BEGIN: ReCAPTCHA implementation example. -->
    <div id="recaptcha-demo" class="g-recaptcha" data-sitekey="6LfP0CITAAAAAHq9FOgCo7v_fb0-pmmH9VW3ziFs" data-callback="onSuccess" data-bind="recaptcha-demo-submit"><div class="grecaptcha-badge" style="width: 256px; height: 60px; transition: right 0.3s ease 0s; position: fixed; bottom: 14px; right: -186px; box-shadow: 0px 0px 5px gray;"><div class="grecaptcha-logo"><iframe src="https://www.google.com/recaptcha/api2/anchor?k=6LfP0CITAAAAAHq9FOgCo7v_fb0-pmmH9VW3ziFs&amp;co=aHR0cHM6Ly93d3cuZ29vZ2xlLmNvbTo0NDM.&amp;hl=en&amp;v=r20170213115309&amp;size=invisible&amp;cb=uror1hlow5a" title="recaptcha widget" scrolling="no" name="undefined" width="256" height="60" frameborder="0"></iframe></div><div class="grecaptcha-error"></div><textarea id="g-recaptcha-response" name="g-recaptcha-response" class="g-recaptcha-response" style="width: 250px; height: 40px; border: 1px solid #c1c1c1; margin: 10px 25px; padding: 0px; resize: none;  display: none; "></textarea></div></div>
    <script>
        var onSuccess = function (response) {
            var errorDivs = document.getElementsByClassName("recaptcha-error");
            if (errorDivs.length) {
                errorDivs[0].className = "";
            }
            var errorMsgs = document.getElementsByClassName("recaptcha-error-message");
            if (errorMsgs.length) {
                errorMsgs[0].parentNode.removeChild(errorMsgs[0]);
            }
            document.getElementById("recaptcha-demo-form").submit();
        };
    </script><!-- Optional noscript fallback. --><!-- END: ReCAPTCHA implementation example. --></div>
    
  5. Put the following code instead of the block you've just cut:
  6. <input type="submit">
    <textarea name="g-recaptcha-response">%g-recaptcha-response%</textarea>
    
    Where %g-recaptcha-response% - is an answer token you’ve got from our service.
  7. You will see “Submit query” button.
    Press the button to submit the form with g-recaptcha-response and all other form data to the website.

reCAPTCHA V3

reCAPTCHA V3 is the newest type of captcha from Google. It has no challenge so there is no need for user interaction. Instead it uses a "humanity" rating - score.

reCAPTCHA V3 technically is quite similar to reCAPTCHA V2: customer receives a token from reCAPTCHA API which is then sent inside a POST request to the target website and verified via reCAPTCHA API.

The difference is now reCAPTCHA API returns rating of a user detecting whether he was a real human or a bot. This rating is called score and could be a number from 0.1 to 0.9. This score is passed to the website which then decides what to do with the user request.

Also there is a new parameter action allowing to process user actions on the website differently. After the verification of token reCAPTCHA API returns the name of the action user performed.

Our approach for solving reCAPTCHA V3
We've performed many experiments and figured out that if a user got score 0.1 on some website then he is likely to get the same score on other websites.

We are detecting the scores of our workers. Then when we've got a request for solving reCAPTCHA V3 with the minimal rating min_score we pass the captcha to the worker with the requested rating or higher. Most of the requests will get the requested rating on targer websites with reCAPTCHA V3.

How to solve reCAPTCHA V3 using 2captcha:

  1. First you've got to be sure the target website is actually using reCAPTCHA V3

    There should be V3 if:

    • there is no captcha and no images to click on
    • api.js script is loading with the render=sitekey parameter, for example:
      https://www.google.com/recaptcha/api.js?render=6LfZil0UAAAAAAdm1Dpzsw9q0F11-bmervx9g5fE
    • clients array of ___grecaptcha_cfg object is using index 100000: ___grecaptcha_cfg.clients[100000]

  2. To start solving reCAPTCHA V3 using our API first you've got to find three parameters:

    sitekey - this parameter could be obtained from the URI of api.js as a value of render parameter. It could also be found inside URI of iframe with reCAPTCHA, in javascript code of the website where it's calling grecaptcha.execute function or in ___grecaptcha_cfg configuration object.

    action - you've got to find this inspecting javascript code of the website looking for call of grecaptcha.execute function. Example: grecaptcha.execute('6LfZil0UAAAAAAdm1Dpzsw9q0F11-bmervx9g5fE', {action: do_something}).
    Sometimes it's really hard to find it and you've got to dig through all js-files loaded by website. You may also try to find the value of action parameter inside ___grecaptcha_cfg configuration object but usually it's undefined. In that case you have to call grecaptcha.execute and inspect javascript code. If you can't find it try to use the default value "verify" - our API will use it if you don't provide action in your request.

    pageurl - full URL of the page where you see the reCAPTCHA V3.

    Now you need to understand the score you need to solve V3. You can't predict what score is acceptable for the website you want to solve at. It can only be figured out by trial and error. The lowest score is 0.1 which means "robot", the highest is 0.9 which means "human". But most sites uses thresholds from 0.2 to 0.5 because real humans receive a low score oftenly. Our service is able to provide solutions which requires the score of 0.3. Higher score is extreamly rare among workers.

  3. Having all necessary parameters stated above you may send request to our API.

  4. Submit a HTTP GET or POST request to our API URL:
    http://2captcha.com/in.php
    with method set to userrecaptcha and version set to v3 along with min_score set to score website requires, sitekey inside googlekey parameter and full page URL as value for pageurl. You have to include action parameter to or else we will use default value verify.

    List of request parameters below.

    URL request sample:

    http://2captcha.com/in.php?key=1abc234de56fab7c89012d34e56fa7b8&method=userrecaptcha&version=v3&action=verify&min_score=0.3
    &googlekey=6LfZil0UAAAAAAdm1Dpzsw9q0F11-bmervx9g5fE&pageurl=http://mysite.com/page/
  5. If everything is fine server will return the ID of your captcha as plain text, like: OK|2122988149 or as JSON {"status":1,"request":"2122988149"} if json parameter was used.

    If something went wrong server will return an error. See Error Handling chapter for the list of errors.

  6. Make a 10-15 seconds timeout and submit a HTTP GET request to our API http://2captcha.com/res.php providing the captcha ID. The list of parameters is in the table below.

    If everything is fine and your captcha is solved server will return the answer as plain text or as JSON. The answer is a token like this:

    03AHJ_Vuve5Asa4koK3KSMyUkCq0vUFCR5Im4CwB7PzO3dCxIo11i53epEraq-uBO5mVm2XRikL8iKOWr0aG50sCuej9bXx5qcviUGSm4iK4NC_Q88flavWhaTXSh0VxoihBwBjXxwXuJZ-WGN5Sy4dtUl2wbpMqAj8Zwup1vyCaQJWFvRjYGWJ_TQBKTXNB5CCOgncqLetmJ6B6Cos7qoQyaB8ZzBOTGf5KSP6e-K9niYs772f53Oof6aJeSUDNjiKG9gN3FTrdwKwdnAwEYX-F37sI_vLB1Zs8NQo0PObHYy0b0sf7WSLkzzcIgW9GR0FwcCCm1P8lB--gf50q5BMkiRH7osm4DoUgsjc_XyQiEmQmxl5sqZP7aKsaE-EM00x59XsPzD3m3YI6SRCFRUevSyumBd7KmXE8VuzIO9lgnnbka4-eZynZa6vbB9cO3QjLH0xSG3--o-fxrOuphwfrtwvvi2FGfpTexWvxhqWICMFTTjFBCEGEgj7_IFWEKirXW2RTZCVF0Gid7EtIsoEeZkPbrcUISGmgtiJkJ_KojuKwImF0G0CsTlxYTOU2sPsd5o1JDt65wGniQR2IZufnPbbK76Yh_KI2DY4cUxMfcb2fAXcFMc9dcpHg6f9wBXhUtFYTu6pi5LhhGuhpkiGcv6vWYNxMrpWJW_pV7q8mPilwkAP-zw5MJxkgijl2wDMpM-UUQ_k37FVtf-ndbQAIPG7S469doZMmb5IZYgvcB4ojqCW3Vz6Q

    If the captcha is not solved yet server will return CAPCHA_NOT_READY. Just repeat your request in 5 seconds.

    If something went wrong server will return an error. See Error Handling chapter for the list of errors.

    Sample request:

    http://2captcha.com/res.php?key=1abc234de56fab7c89012d34e56fa7b8&action=get&json=1&id=2122988149
  7. After receiving the token from our API you've got to use it properly on the target website. Best way to understant that is to check the requests sent to site when you act as a normal user. Most browsers has developer's console tool where you should check Network tab.

    Usually token is sent using POST request. It could be g-recaptcha-response just like reCAPTCHA V2 does or g-recaptcha-response-100000. It could be other parameter too. So you've got to inspect the requests and find out how exactly the token supposed to be sent. Then you have to compose your request accordingly.

  8. Now when you have successfully submit the token you may tell us if it worked or not. If not we will refund the money you spent on this token. If it was successfully accepted we will set the worker who solved this captcha as the priority solver for you. Besides we will gather statistics regarding V3 solution which will help us to further investigate this new type of captchas and make our service better.

    To let us know whether it worked or not please send the request to http://2captcha.com/res.php with your API Key in key parameter with ID of the captcha in id parameter and indicating action parameter. Next to mention is reportgood if token was accepted successfully or reportbad if token wasn't accepted respectfully.

    Request examples:

    http://2captcha.com/res.php?key=1abc234de56fab7c89012d34e56fa7b8&action=reportbad&id=2122988149
    http://2captcha.com/res.php?key=1abc234de56fab7c89012d34e56fa7b8&action=reportgood&id=2122988149

    Important: complains for captcha types solved with token are not shown on the website. But we proceed with every report and gather the statistics. We will implement this complain display feature in future.

reCAPTCHA Enterprise

reCAPTCHA Enterprise is the newest type of captcha from Google. It can be used as V2 and V3 and provides website administrators an option to report the interaction result - was it a human or not.

How to solve reCAPTCHA Enterprise using 2captcha:

  1. First step is to determine that Enterpise version of reCAPTCHA is used. The main Enterprise attributes are:

    • enterprise.js script instead of api.js is included on the page <script src="https://recaptcha.net/recaptcha/enterprise.js" async="" defer=""></script>
    • grecaptcha.enterprise.METHOD calls in javascript code of the website instead of grecaptcha.METHOD

  2. Then you need to determine which implementation is used: V2, V2 Invisible or V3. It is quite easy, just follow the flowchart below, it works in 99% of cases.

  3. Find captcha parameters the same way it is done for V2 or V3.

    For V2 implementations there can be optional additional data used: in most cases that is a custom string value defined in s or data-s parameter. You can pass this data inside data-s request parameter.

    For V3 you may also need the action value. To find it you need to dive into javascript code of the website and find the grecaptcha.enterprise.execute call. Action is passed to this call. But keep in mind that action is optional and can remain undefined.

  4. Add an additional parameter enterprise=1 to your request to in.php endpoint and interact with our API the same way it is done when solving V2 or solving V3 to get the token, then use the token in the same way it is used on your target website.

  5. reCAPTCHA V2 (old method)

    Solving reCAPTCHA V2 with that old method is less accurate and more compex. So we recommend to use the new method. But the old method is cheaper and we still support it.

    We can solve recaptchas with different grids like 3x3, 2x4, 4x4.

    Also you can solve reCAPTCHA V2 with ClickCaptcha method if it's more suitable for you.

    And of course we support reCAPTCHA V2 challenges when you have to select around an object or few objects. Read more here.

    To solve the reCAPTCHA V2 you have to:

    1. Click on initial reCAPTCHA's checkbox. You will get a set of images and instruction that tells you what to click. Actually it's one image with the grid on it.

    2. Optionally: determine the grid and define it in your request with recaptchacols and recaptcharows parameters.
      If not defined we'll check the size of the image. If it's 300x300px we put 3x3 grid on it. If the size is different we put 4x4 grid.

    3. Submit a HTTP POST request to our API URL: http://2captcha.com/in.php including recaptcha parameter set to 1.

      Server accepts images in multipart or base64 format. You have to send only the image set without the grid and blue box.

      Also you can provide instructions as an image using imginstructions parameter. For more info please check the full list of parameters in the table below.

    4. Server will return captcha ID or an error code if something went wrong.

    5. Make a 5 seconds timeout and submit a HTTP GET request to our API URL: http://2captcha.com/res.php to get the result.

      If captcha is already solved server will return the answer with numbers of grid cells that you need to click like: OK|click:3/8/9.

      Grid cells are numbered starting from number 1 from left to right and from top to bottom.

      If captcha is not solved yet server will return CAPCHA_NOT_READY result. Repeat your request in 5 seconds.

      If something went wrong server will return an error code.

    6. You simulate clicks on cells from the answer.

    7. If reCAPTCHA updates the set of images you can send us new request with an additional parameter previousID and the ID of previous request as a value. Then our worker will check only new images that were not selected by previous worker.

    8. Also you can proivde additional parameter can_no_answer in case if there's no images to click left. Worker will see a button to confirm that there's no corresponding images and API will return No_matching_images as answer.

    Canvas method

    In case when reCAPTCHA challenge is to select around object you can pass canvas parameter set to 1.

    Server will return the result in the following format: canvas:x,y,x,y,x,y;x,y,x,y,x,y;

    Where each pair of x and y are coordinates of points you need to click to select an area around object. If there are more than one area, coordininates of areas will be separated by semicolon.

    For example:
    canvas:5,5,3,91,93,90,90,7,8,6; - one area
    canvas:5,5,3,91,93,90,90,7,8,6;208,211,208,287,294,294,293,209,207,210; - two areas
    Point 0,0 is top left corner of the image.

    You need to click on these points one by one to pass the challenge.

    RotateCaptcha

    RotateCaptcha is a type of captcha where you have to rotate images to solve it. The most popular is FunCaptcha by Arkose Labs.

    To solve RotateCaptcha you have to:

    1. Get an image or several images that should be rotated.

    2. Optionally: determine the angle for one rotation step and provide it as a value for angle parameter.
      If not defined we'll use the default value for FunCaptcha: 40 degrees.

      The full list of parameters is in the table below.

    3. Submit images to our server with HTTP POST request to our API URL: http://2captcha.com/in.php setting method parameter to rotatecaptcha. Server accepts images only in multipart format.

      Server will return captcha ID or an error code if something went wrong.

    4. Make a 5 seconds timeout and submit a HTTP GET request to our API URL: http://2captcha.com/res.php to get the result.

      If captcha is already solved server will return the answer with angles for each image like: OK|40|200|-120.

    Arkose Labs FunCaptcha

    Now we provide a method to solve Arkose Labs captcha (ex. FunCaptcha) with a token.

    The method is pretty simple:

    1. You need to locate two values on the page with Arkose Labs captcha

      • - Public key
      • - Service URL (surl)

      Public key can be found inside data-pkey parameter of funcaptcha's div element or inside an input element with name fc-token - just extract the key indicated after pk from the value of this element.
      Service Url can be also found in fc-token - that is a value of surl parameter.
      Service Url is optional parameter and if you don't provide it we use a default value that is valid for most cases, but we recommend you to provide it.

    2. Submit a HTTP GET or POST request to our API URL: http://2captcha.com/in.php with method set to funcaptcha, provide values found on previous step for publickey and surl parameter and full page URL as value for pageurl.
      You can find the full list of parameters in the table below.

    3. If everything is fine server will return the ID of your captcha as plain text, like: OK|2122988149 or as JSON {"status":1,"request":"2122988149"} if json parameter was used.
      Otherwise server will return an error code.

    4. Make a 10-20 seconds timeout then submit a HTTP GET request to our API URL: http://2captcha.com/res.php to get the result.

          "captchakey": "PUZZLE_Abc1dEFghIJKLM2no34P56q7rStu8v",
          "challengekey": "y1Pu234nCwq56WnqB7y8TSZq0Qzp0ltK",
          "answer": "0xax8ex0xax84x0xkx7qx0xux7qx0xux7gx0x18x7gx0x1sx76x0x26x6ix0x2qx6ix0x3ex68x0"
      }

      If captcha is not solved yet server will return CAPCHA_NOT_READY result. Repeat your request in 5 seconds.

      If something went wrong server will return an error code.

    5. Use the values returned in your request to the target website passing them in the corresponding request fields:

      • capy_captchakey
      • capy_challengekey
      • capy_answer

    id Integer Yes ID of captcha returned by in.php.
    json Integer
    Default: 0
    No 0 - server will send the response as plain text
    1 - tells the server to send the response as JSON

    Request URL example:

    TikTok

    TikTok provide it's own captcha with different types of challenges: puzzle, select similar objects, etc.

    Important: the methos is cookies-based. Cookies MUST be used within 3 seconds after our worker solved the captcha.

    Due to that you need to get the solution from our API as fast as possible and use it immediately.
    There are few methods to get the response immediately:

    1. Use WebSocket API - the most efficient and recommended method.
    2. Use Pingback - alternative method for cases when you can not use WebSocket API for some reason.
    3. If for some reason you can't use any of mentioned options, try to decrease the interval between the requests to res.php API endpoint. But in such cases there's a big risk of exceeding the limits especially if you solve multiple captchas of this type simultaneously.

    To bypass TikTok captcha:

    1. Find a values for aid and host parameters. The easiest way to do that is to redefine renderCaptcha function like this:
      renderCaptcha = ({aid, host}) => console.log(`aid: ${aid}, host: ${host}`)
      Just run this code in the javascript console of your browser and then perform an action that leads to the captcha challenge. The values will be printed in the console.
      It's enough to do that once. Values will be static for each page where you bypass the captcha.
    2. Clean your cookies and open a page where you need to bypass a captcha challenge. DO NOT PERFORM the action that leads to the captcha challenge.
    3. Get all of the cookies set by the website.
    4. Use all of the parameters required in a request to our API: cookies, aid, host and pageurl.
      When using HTTP API (in.php, res.php) cookies are sent as a string that contains key:value pairs separated by semicolon. For example: name:value;other_name:value2;one_more_cookie:value3. Do not include a domain name and other attributes.
    5. Get a response from our API. It will contain a set of cookies that you should apply in your browser or http client.
      Use the original domain cookies if needed when setting the cookies.
      After setting the cookies perform the action that is captcha protected (login or sign up button click, etc). If everything is fine and done within 3 seconds then captcha will not be displayed.
    6. JSON response example:

      {
          "status": 1,
          "request":"tt_webid:6854206562317010438;tt_webid_v2:6854206562317010438;SLARDAR_WEB_ID:c0fb77f5-ceb6-4d16-a066-61f19df1593e;s_v_web_id:verify_kd4reawo_zpQVF8KK_FFMI_4zuE_8NiQ_hayRdXyiKYtZ",
          "cookies": {
              "tt_webid": "6854206562317010438",
              "tt_webid_v2": "6854206562317010438",
              "SLARDAR_WEB_ID": "c0fb77f5-ceb6-4d16-a066-61f19df1593e",
              "s_v_web_id": "verify_kd4reawo_zpQVF8KK_FFMI_4zuE_8NiQ_hayRdXyiKYtZ"
          }
      }

      Plain text response example:

      OK|tt_webid:6854206562317010438;tt_webid_v2:6854206562317010438;SLARDAR_WEB_ID:c0fb77f5-ceb6-4d16-a066-61f19df1593e;s_v_web_id:verify_kd4reawo_zpQVF8KK_FFMI_4zuE_8NiQ_hayRdXyiKYtZ

    Error Handling

    It's very important to use proper error handling in your code to avoid suspension of your account and service interruption.

    Take a look on debugging method provided by our API. It can help you to identify the root or the error.

    Normally if something is wrong with your request server will return an error.
    Below you can find tables with lists of errors with descriptions:

    Errors can be returned as plain text or as JSON if you provided json=1 parameter.

    In very rare cases server can return HTML page with error text like 500 or 502 - please keep it in mind and handle such cases correctly.
    If you received anything that doesn't looks like the answer or error code - make a 5 seconds timeout and then retry your request.

    List of in.php errors

    Error code Description Action
    ERROR_WRONG_USER_KEY You've provided key parameter value in incorrect format, it should contain 32 symbols. Stop sending requests. Check your API key.
    ERROR_KEY_DOES_NOT_EXIST The key you've provided does not exists. Stop sending requests. Check your API key.
    ERROR_ZERO_BALANCE You don't have funds on your account. Stop sending requests. Deposit your account to continue solving captchas.
    ERROR_PAGEURL pageurl parameter is missing in your request. Stop sending requests and change your code to provide valid pageurl parameter.
    More info.
    ERROR_NO_SLOT_AVAILABLE You can receive this error in two cases:
    1. If you solve token-based captchas (reCAPTCHA, hCaptcha, ArkoseLabs FunCaptcha, GeeTest, etc): the queue of your captchas that are not distributed to workers is too long. Queue limit changes dynamically and depends on total amount of captchas awaiting solution and usually it’s between 50 and 100 captchas.
    2. If you solve Normal Captcha: your maximum rate for normal captchas is lower than current rate on the server.
    You can change your maximum rate in your account's settings.
    If you received this error, don't try to submit your request again immediately. Make 2-3 seconds timeout and then retry to submit your request.
    ERROR_ZERO_CAPTCHA_FILESIZE Image size is less than 100 bytes. Check the image file.
    ERROR_TOO_BIG_CAPTCHA_FILESIZE Image size is more than 100 kB. Check the image file.
    ERROR_WRONG_FILE_EXTENSION Image file has unsupported extension. Accepted extensions: jpg, jpeg, gif, png. Check the image file.
    ERROR_IMAGE_TYPE_NOT_SUPPORTED Server can't recognize image file type. Check the image file.
    ERROR_UPLOAD Server can't get file data from your POST-request.
    That happens if your POST-request is malformed or base64 data is not a valid base64 image.
    You got to fix your code that makes POST request.
    ERROR_IP_NOT_ALLOWED The request is sent from the IP that is not on the list of your allowed IPs. Check the list of your allowed IPs here.
    IP_BANNED Your IP address is banned due to many frequent attempts to access the server using wrong authorization keys. Ban will be automatically lifted after 5 minutes.
    ERROR_BAD_TOKEN_OR_PAGEURL You can get this error code when sending reCAPTCHA V2. That happens if your request contains invalid pair of googlekey and pageurl. The common reason for that is that reCAPTCHA is loaded inside an iframe hosted on another domain/subdomain. Explore code of the page carefully to find valid pageurl and sitekey values.
    ERROR_GOOGLEKEY You can get this error code when sending reCAPTCHA V2. That means that sitekey value provided in your request is incorrect: it's blank or malformed. Check your code that gets the sitekey and makes requests to our API.
    ERROR_WRONG_GOOGLEKEY googlekey parameter is missing in your request Check your code that gets the sitekey and makes requests to our API.
    ERROR_CAPTCHAIMAGE_BLOCKED You've sent an image that is marked in our database as unrecognizable.
    Usually that happens if the website where you found the captcha stopped sending you captchas and started to send "deny access" image.
    Try to override website's limitations.
    TOO_MANY_BAD_IMAGES You are sending too many unrecognizable images Make sure that your last captchas are visible and check unrecognizable images we saved for analisys. Then fix your software to submit images properly.
    MAX_USER_TURN You made more than 60 requests to in.php within 3 seconds.
    Your account is banned for 10 seconds. Ban will be lifted automatically.
    Set at least 100 ms timeout between requests to in.php.
    ERROR: NNNN Where NNNN is numeric error code.
    You exceeded request limit and your account is temporary suspended.
    You should set proper timeouts. Please refer to Request limits for more info.
    ERROR_BAD_PARAMETERS The error code is returned if some required parameters are missing in your request or the values have incorrect format.
    For example if you submit reCAPTCHA as image but your request is missing an instruction for workers. Or if you submit reCAPTCHA V2 or TikTok captcha with cookies string that has incorrect format.
    Check that your request contains all the required parameters and the values are in proper format.
    Use debug mode to see which values you send to our API.
    ERROR_BAD_PROXY You can get this error code when sending a captcha via proxy server which is marked as BAD by our API. Use a different proxy server in your requests.

    List of res.php errors

    Error code Description Action
    CAPCHA_NOT_READY Your captcha is not solved yet. Make 5 seconds timeout and repeat your request.
    ERROR_CAPTCHA_UNSOLVABLE We are unable to solve your captcha - three of our workers were unable solve it or we didn't get an answer within 90 seconds (300 seconds for reCAPTCHA V2).
    We will not charge you for that request.
    You can retry to send your captcha.
    ERROR_WRONG_USER_KEY You've provided key parameter value in incorrect format, it should contain 32 symbols. Stop sending requests. Check your API key.
    ERROR_KEY_DOES_NOT_EXIST The key you've provided does not exists. Stop sending requests. Check your API key.
    ERROR_WRONG_ID_FORMAT You've provided captcha ID in wrong format. The ID can contain numbers only. Check the ID of captcha or your code that gets the ID.
    ERROR_WRONG_CAPTCHA_ID You've provided incorrect captcha ID. Check the ID of captcha or your code that gets the ID.
    ERROR_BAD_DUPLICATES Error is returned when 100% accuracy feature is enabled. The error means that max numbers of tries is reached but min number of matches not found. You can retry to send your captcha again.
    REPORT_NOT_RECORDED Error is returned to your report request if you already complained lots of correctly solved captchas (more than 40%). Or if more than 15 minutes passed after you submitted the captcha. Make sure that you're sending complain requests only for incorrectly solved captchas.
    ERROR_DUPLICATE_REPORT Error is returned to your report request if you are trying to report the same captcha more than once. Make sure that you're sending only one report for each captcha.
    ERROR: NNNN Where NNNN is numeric error code.
    You exceeded request limit and your account is temporary suspended.
    You should set proper timeouts. Please refer to Request limits for more info.
    ERROR_IP_ADDRES You can receive this error code when registering a pingback (callback) IP or domain.
    That happes if your request is coming from an IP address that doesn't match the IP address of your pingback IP or domain.
    Make the request from the IP address matching your IP or domain for pingback.
    ERROR_TOKEN_EXPIRED You can receive this error code when sending GeeTest.
    That error means that challenge value you provided is expired.
    If you always receive this error code that means that we're unable to solve GeeTest on this website.
    ERROR_EMPTY_ACTION Action parameter is missing or no value is provided for action parameter. Check your request parameters and add the neccessary value, e.g. get or getbalance.
    ERROR_PROXY_CONNECTION_FAILED You can get this error code if we were unable to load a captcha through your proxy server. The proxy will be marked as BAD by our API and we will not accept requests with the proxy during 10 minutes.
    You will recieve ERROR_BAD_PROXY code from in.php API endpoint in such case.
    Use a different proxy server in your requests.

    Debugging

    Sometimes it can be hard to find to undrestand why our API returns an error code when you make a request that looks correct.

    We provide a debugging method that can help you to find the root of the problem showing what exactly our API recevied from you.

    The method can be used both on in.php and res.php API endpoints for any request.

    Add an additional parameter debug_dump=1 to your request and our server will return a dump of request parameters that received by our API.

    Request example:

    http://2captcha.com/in.php?key=1abc234de56fab7c89012d34e56fa7b8&method=userrecaptcha&googlekey=6Le-wvkSVVABCPBMRTvw0Q4Muexq1bi0DJwx_mJ-&json=1&header_acao=1&pageurl=http://mysite.com/page/with/recaptcha/&pingback=http://1.2.3.4/pingback_handler/&debug_dump=1
    

    Response example:

    array(8) {
      ["key"]=>
      string(32) "1abc234de56fab7c89012d34e56fa7b8"
      ["method"]=>
      string(13) "userrecaptcha"
      ["googlekey"]=>
      string(40) "6Le-wvkSVVABCPBMRTvw0Q4Muexq1bi0DJwx_mJ-"
      ["json"]=>
      string(1) "1"
      ["header_acao"]=>
      string(1) "1"
      ["pageurl"]=>
      string(38) "http://mysite.com/page/with/recaptcha/"
      ["pingback"]=>
      string(32) "http://1.2.3.4/pingback_handler/"
      ["debug_dump"]=>
      string(1) "1"
    }
    array(0) {
    }
    array(0) {
    }
    {"status":0,"request":"ERROR_KEY_DOES_NOT_EXIST"} 
    

    Using this method you will be able to easily identify cases when your request contains invalid data or missing required parameters.

    Request limits

    Please remember and understand that each of your requests to our API generates multuple requests to our databases. That's why we ask to set proper timeouts for your requests and use proper error handling for cases when server returns an error (error message, HTTP error or HTML page with error).

    For example:

    • If server returns ERROR_NO_SLOT_AVAILABLE make a 5 seconds timeout before sending next request.
    • If server returns ERROR_ZERO_BALANCE set the timeout to 60 seconds.
    • After uploading a captcha wait a least 5 seconds (10-20 for recaptcha) and only then try to get the answer.
    • If captcha is not solved yet - retry in 5 seconds.

    If your timeouts are configured incorrectly your account or IP address will be temporary blocked and server will return an error. See the list of error codes in the table below.

    List of error codes for request limitations

    Error code Blocking time Blocking reason
    ERROR: 1001 10 minutes You received 120 ERROR_NO_SLOT_AVAILABLE errors in one minute because your current bid is lower than current bid on the server
    ERROR: 1002 5 minutes You received 120 ERROR_ZERO_BALANCE errors in one minute because your balance is out
    ERROR: 1003 30 seconds You are getting ERROR_NO_SLOT_AVAILABLE because you are uploading many captchas and server has a long queue of your captchas that are not distributed to workers.
    You received three times more errors than amount of captchas you sent (but not less than 120 errors). Increase the timeout if you see this error.
    ERROR: 1004 10 minutes Your IP address is blocked because there were 5 requests with incorrect API key from your IP.
    ERROR: 1005 5 minutes You are making too many requests to res.php to get answers.
    We use the following rule to block your account: R > C * 20 + 1200
    Where:
    R - the amount of your requests
    C - the amount of captchas you've uploaded
    That means that you don't have to make more than 20 requests to res.php per each captcha.
    Please remember that balance request sent to res.php also counts!
    To get your answer faster without a risk to be blocked you can use pingback feature and we will send you the answer when your captcha is solved.
    MAX_USER_TURN 10 seconds You made more than 60 requests to in.php within 3 seconds. Set at least 100 ms timeout between requests to in.php.

    Using proxies

    Proxies can be used to solve most types of javascript-based captchas:


    Proxy allows to solve the captcha from the same IP address as you load the page.
    Using proxies is not obligatory in most cases. But for some kind of protection you should use it. For example: Cloudflare and Datadome protection pages require IP matching.
    Also good proxies with regular rotation can raise the speed and success rate for Arkose Labs FunCaptcha.

    Proxies are not supported for reCAPTCHA V3 and Enterprise V3 as proxies dramatically decrease the success rate for this types of captcha.

    If you send us the proxy, we check it's availability trying to open the website through you proxy, and if we can't do that we will not use your proxy.
    If we're able to use your proxy - we'll load the reCAPTCHA through it for solving.

    We don't have our own proxy servers that we can offer to you so you have to use 3rd-party services or setup your own proxy.

    We support the following proxy types: SOCKS4, SOCKS5, HTTP, HTTPS with authentication by IP address or login and password.

    If your proxy uses IP authentication you have to add our IP addresses to the list of allowed IPs of the proxy:
    138.201.188.166

    Then provide your proxy IP address and port as a value for proxy parameter.
    And the type of your proxy as a value for proxytype parameter.

    If your proxy uses login/password authentication you have to include your credentials in proxy parameter.

    POST parameters for proxies

    POST parameter Type Required Description
    proxy String No Format for IP authentication: IP_address:PORT
    Example: proxy=123.123.123.123:3128
    Format for login/password authentication: login:password@IP_address:PORT
    Example: proxy=proxyuser:strongPassword@123.123.123.123:3128
    proxytype String No Type of your proxy: HTTP, HTTPS, SOCKS4, SOCKS5.
    Example: proxytype=SOCKS4

    Pingback (callback)

    We provide a pingback (callback) option that allows you to get the answer for your captcha automatically when it's ready.
    It allows you to get answers without making requests to http://2captcha.com/res.php and also allows you to avoid account suspension.

    To receive automated pingback you have to:

    • Register your pingback domain/IP address.
    • Provide your pingback URL as a value for pingback parameter of your request to http://2captcha.com/in.php.
    • Process HTTP POST request with URLencoded form data (application/x-www-form-urlencoded) coming from our server to your pingback URL. The request contains two parameters: id - captcha ID and code - the answer.

    Incoming pingback request example:

    id=51555263943&code=ANSWER

    You can use any pingback URL pointing to your registered domain/IP address so your URL can include custom parameters.
    But there's one limitation: if you will submit your captcha with GET request and use URL that contains multiple parameters like http://mysite.com/pingback/?myId=1&myCat=2&something_else=test then you will receive pingback to URL with only the first parameter ?myId=1. To avoid that use POST request with multipart/form-data.

    Manage pingback addresses

    You can manage your pingback addresses on pingback management page or making HTTP GET requests to http://2captcha.com/res.php
    Request parameters are described in the table below.

    Important: pingback domain/IP address can be registered only from the same IP address so you got to send register request from your server.

    List of GET request parameters for http://2captcha.com/res.php

    GET parameter Type Required Description
    key String Yes your API key
    action String Yes add_pingback - register new pingback URL
    get_pingback - get the list of your pingback URLs
    del_pingback - delete pingback URL
    addr String - Your pingback URL.
    For example: http://mysite.com/pingback/url/ or 123.123.123.123/pingback/url/
    You can use 'all' value together with del_pingback to delete all your URLs.
    json Integer
    Default: 0
    No 0 - server will send the response as plain text
    1 - tells the server to send the response as JSON

    Request examples

    Register pingback domain/IP:

    http://2captcha.com/res.php?key=1abc234de56fab7c89012d34e56fa7b8&action=add_pingback&addr=mysite.com

    List pingback domains/IPs:

    Reporting answers

    Reporting answers is not required to solve capthcas. But it can help you to cut expenses and increase the accuracy. We described why it is important to report answers in our blog.

    We recommend to report both correct and incorrect asnwers for all types of captchas.

    If the answer is not accepted by target website use reportbad method to inform us about that. The answer will be rechecked and you will receive a refund for incorrect answer.

    If the answer was accepted successfully use reportgood method to indicate that. That will allow us to increase the accuracy for future requests.

    Important: don't try to report correct answers with reportbad. If you will do that then we will block this method for your account.

    Reports for captchas with token like reCAPTCHA V2/V3, KeyCaptcha, FunCaptcha are not visible in the user interface or the dashboard. But we gather the statistics on these reports to increase the success rate for these captchas.
