GeeTest CAPTCHA solver

GeeTest CAPTCHA bypass API service

With our serivce your can easily bypass both versions of Geetest: v3 and v4, but first you need to indetify which version is used by your target website.
There are few attributes that can be used for the identification:

• v3 uses initGeetest initialization function and v4 uses initGeetest4
• v3 loads gt.js script, but v4 loads gt4.js

GeeTest v3

1. Find the following GeeTest captcha parameters on the target website (usually you can find them inside initGeetest function):

   gt - public website key (static)
   challenge - dynamic challenge key
   api_server - API domain (optional)

   Important: you should get a new `challenge` value for each request to our API. Once captcha was loaded on the page the `challenge` value becomes invalid. You should inspect requests made to the website when page is loaded to identify a request that gets a new `challenge` value. Then you should make such request each time to get a valid `challenge` value.

2. Send these parameters to 2Captcha API. If captcha is already solved server will return the response in JSON. The response contains three values: challenge, validate and seccode:

   {
   "challenge": "1a2b3456cd67890e12345fab678901c2de",
   "validate": "09fe8d7c6ba54f32e1dcb0a9fedc8765",
   "seccode": "12fe3d4c56789ba01f2e345d6789c012|jordan"
   }Copy code snippet

3. Use the values received from our API to submit your request to the target website placing the values into corresponding request fields:

   geetest_challenge
   geetest_validate
   geetest_seccodeCopy code snippet

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

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.

   <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. Wait for the result, which may look like this:

   {
    "captcha_id": "e392e1d7fd421dc63325744d5a2b9c73",
    "lot_number": "532c4ca58e3f4adb8ef96bfa222e623e",

    "gen_time": "1679073037",
    "captcha_output": "c3rHzKlQXuv9xJe_l2wqb7ypWdFpbyZ_pk1ODXGTOdHKE5cJFer1r1jNTt2n5muwLzs5HOQ39D2lFjzqcygPO7ftaMFLXVMTCZuD8PkD4j10_vnvF0keeTTjbJaC0jq7btCE12-eN6fF6WPtHEoXLLXqkb8HaISjG5znAuZDMZ055HsCE6S7iyiaJYv_l0Sm1atkF0VEAYaKrEhQRYHus35X6FqIoRvVo1ISyCZGnjw="

3. 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.
