Introduction

Captcha-solver is an API service for automated captcha solving: reCAPTCHA v2, reCAPTCHA v3, Cloudflare Turnstile. The request/response format is compatible with anti-captcha (createTask/getTaskResult), so existing client libraries work without rewriting — just point them at our base URL.

You get an API key right after registration, and pay only for solved tasks.
