## **What is GeeTest?**
GeeTest is a widely used CAPTCHA provider that challenges users with various types of captchas, such as slides, puzzles, and AI-based captchas. While most sites use v3, some have transitioned to v4. Example responses for each version might look like:
* **v3**: `{'geetest_challenge': ..., 'geetest_validate': ..., 'geetest_seccode': ...}`
* **v4**: `{'captcha_id': ..., 'lot_number': ..., 'pass_token': ..., 'captcha_output': ...}`
