reCAPTCHA v3 Solver API
Integrate reCAPTCHA v3 solving into your automation through one stable REST endpoint. Send the target details and receive a ready-to-use solution without maintaining custom bypass logic.

reCAPTCHA v3, without custom bypass code.
A predictable three-step flow that stays the same even when reCAPTCHA v3 changes its protection.
Send the site key and the page_action your target page passes to execute(). We return a token plus the matching _GRECAPTCHA cookie and browser fingerprint, so follow-up requests stay consistent.
Submit the target
Send the page URL and the challenge-specific fields in a single API request.
We handle the challenge
CaptchaSolv routes the task to a specialized solver and tracks it until completion.
Use the solution
Receive the token, headers, cookies, or sensor payload required by your next request.
The same endpoint and response envelope across every supported solver.
