Friendly Captcha

Friendly Captcha Siteverify API

The siteverify endpoint validates a Friendly Captcha solution token. The server POSTs the token and API key (with optional sitekey) and receives a JSON response indicating success, risk score, IP intelligence, bot detection signals, and any error codes. This is the canonical server-side check for protected form submissions and API calls.
