Cloudflare Turnstile with an action name. Our server verifies the token against Cloudflare's siteverify endpoint.

What is this captcha demo for?
It gives you real captcha widgets to test against: your automation scripts, a browser extension, or tokens from a solver API. Each form sends the token to our server, which checks it with Google or Cloudflare and shows the exact verification response, the same way a real site would.
Are these real reCAPTCHA and Turnstile keys?
Yes. The demos use captchano.com's own reCAPTCHA v2, reCAPTCHA v3 and Turnstile keys, and every token is checked with Google or Cloudflare exactly as a production site would. A token is accepted once; a reused, expired or forged token is rejected with the provider's error code.
How do I solve the demo captcha with the API?
Send a POST to /v1/solve with the type, the URL of this page and the site key shown in the request panel. The response contains a token. Put it in the g-recaptcha-response or cf-turnstile-response field, or verify it directly from the solver playground.
What does the siteverify response mean?
success says whether the provider accepted the token. hostname is the site the token was issued for, and challenge_ts is when it was created. error-codes explains a failure: timeout-or-duplicate means the token was too old or already used, and invalid-input-response means it was malformed or for another key.
Can I test the CaptchaNo browser extension here?
Yes. With the extension installed and connected, the reCAPTCHA and Turnstile demos are solved automatically and a status label appears under the widget. For the image captcha, right-click the image and choose Solve this captcha image with CaptchaNo.
