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.
