CaptchaNo is a captcha solving API for developers who run scrapers, end-to-end tests and AI agents. Send the challenge type, sitekey and page URL in one request and get back a token, cookie or text to submit. The call waits for the result, so there is no polling loop to write, and you can pass your own proxy and user agent so the token matches your session. It supports reCAPTCHA v2, v3 and Enterprise, Cloudflare Turnstile, DataDome and image captchas with the same request shape. Pricing is pay as you go from $1.50 per 1,000 solves with free credit on signup, and failed solves are never billed. There is also an open-source MCP server for Claude, Cursor and VS Code, an n8n node and an Apify actor.
