  - name: reCAPTCHA Site Verify API
    description: >-
      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.
