Captcha Verify

by Captcha verify in Security & trust

x402 APIPassing, checked 5 h ago

Validate a Cloudflare Turnstile, Google reCAPTCHA, or hCaptcha token server-side. You pass your OWN provider secret plus the token from the client; we relay to the provider's siteverify endpoint (never logged) and return the normalized verdict (success, hostname, action, score, error codes). The legitimate backend half of bot protection - no solving, no bypass.
