reCAPTCHA V2

Token-based method for automated solving of reCAPTCHA V2.

The token recived then can be sent to the target website inside g-recaptcha-response form field or passed to a callback function.

Task types

RecaptchaV2TaskProxyless - suitable for most cases. We use our own pool of proxies to solve the captchas
RecaptchaV2Task - used for cases when IP matching is requied on Google service like Google Search, YouTube, etc. Bad proxies will drastically decrease the success rate and increase the solving time.
