GeeTest CAPTCHA V4 demo

How to solve GeeTest v4

1. Open developer's console in your browser and find script element that loads the GeeTest v4 script, you need to grab the captcha_id parameter value from the script src attribute.
   
   An example of a script element from the page:

   <script  src="https://gcaptcha4.geetest.com/load?captcha_id=e392e1d7fd421dc63325744d5a2b9c73&amp;challenge=36056b4d-7453-4153-aaa7-67ac27ccae9c&amp;client_type=web&amp;lang=en&amp;callback=geetest_1679073111173"></script>Copy code snippet

2. Send captcha_id and pageurl to 2Captcha API.

   With SDK (recommended):

   PHP

   // https://github.com/2captcha/2captcha-php
   
   require(__DIR__ . '/../src/autoloader.php');
   
   $solver = new \TwoCaptcha\TwoCaptcha('YOUR_API_KEY');
   
   try {
       $result = $solver->geetest_v4([
         'captchaId' => '42977dc9-a215-4b09-aa14-945ef310d829',
         'url'       => 'https://2captcha.com/demo/geetest-v4',
     ]);
   } catch (\Exception $e) {
       die($e->getMessage());
   }
   
   die('Captcha solved: ' . $result->code);Copy code snippet

   from twocaptcha import TwoCaptcha
   
   api_key = os.getenv('APIKEY_2CAPTCHA', 'YOUR_API_KEY')
   
   solver = TwoCaptcha(api_key)
   
   try:
       result = solver.geetest_v4(captcha_id='42977dc9-a215-4b09-aa14-945ef310d829',
                                  url='https://2captcha.com/demo/geetest-v4')

     pageurl: 'https://2captcha.com/demo/geetest-v4'
   })Copy code snippet

   Manually:

   1. Submit a HTTP GET or POST request to our API URL: https://2captcha.com/in.php with method set to geetest_v4 providing values found on previous step in your request as values for corresponding request parameters and also full page URL as value for pageurl.

      Request URL example:
      https://2captcha.com/in.php?key=1abc234de56fab7c89012d34e56fa7b8&method=geetest_v4&captcha_id=42977dc9-a215-4b09-aa14-945ef310d829&&pageurl=http://2captcha.com/demo/geetest-v4

   2. If everything is fine server will return the ID of your captcha:

      OK|2122988149
      Otherwise server will return an error code.

   3. After 15-20 seconds send GET request to get the result:

      GET https://2captcha.com/res.php?key=YOUR_API_KEY&action=get&id=2122988149
      If captcha is already solved server will respond with the answer.

      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.

3. If captcha is already solved server will return the response in JSON. The response contains five values: captcha_id, lot_number, pass_token, gen_time and captcha_output:

   {
   "captcha_id":"e392e1d7fd421dc63325744d5a2b9c73",
   "lot_number":"81c1ed8e35be4f67a00bf30b578e873a",
   "pass_token":"0b088f4a5c742a912c0cfa2f98cd8e4fb4bd6a0c9389272ea5beac93f632d4e9",
   "gen_time":"1687352616",
   "captcha_output":"fN36ufW6cQN-UMXTCVLbps254G0c0ZnGN5368O2A5_SaEYV9-8U0kUUT-Of9xrdwrV6xLd8XZLJSs6jiWdyZaVBcG0kIoKkl6Bq4IKg0mlQ-zmEgqq1jSwPIEl34mhUMCq3Xmfj2E-H4_kyh-UjSkPSMMTumf97Fe7PFhZJJfui-731XLBFR7WwJsY8S9BXNKtMzQDp7zUWDZjxGxWyC8n1G3Q5jk7oV4ez9zcmF6PymY_sHj3kFyCoa8q9o8FTp"

4. Use the values returned on your target website the same way they’re used once you solve the captcha manually. There can be a form with a set of hidden inputs or a JavaScript callback. Or you can simply build a HTTP requests with the required data.

5. Click on "Check" button to submit the form.
