    FAQs

    Is there a free tier?

    Yes — start on the Free plan to test. Upgrade when you need more volume or fields.

    Do I need SDKs?

    No. It’s plain HTTPS/JSON with copy‑paste cURL/JS. Use any HTTP client you like.

    What’s in the response?

    Free returns disposable + a basic score. Paid plans unlock extended signals (decay, provenance, MX/TLD, etc.).
