reCAPTCHA Site Verify API is one of 3 APIs that [Google reCAPTCHA](https://apis.io/providers/google-recaptcha/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include reCAPTCHA V3, Token Validation, and Verification. The published artifact set on APIs.io includes API documentation.

The reCAPTCHA Site Verify API is the standard verification endpoint for reCAPTCHA v2 and v3 tokens. After a user completes a reCAPTCHA challenge on the frontend, the backend sends the response token to this API to verify the interaction. The API returns whether the verification succeeded, a score (for v3), the action name, and the hostname.
