API

One GET request, JSON back. No key required for the free tier.

Returns the same analysis the web page shows: score, bulkSender, spf, dkim, dmarc (including the full treeWalk path), mx, and a sorted findings array.

Limits

• 25 audits per day, per caller, free.
• One domain per request. Bulk domain lists run through the Apify actor, not this endpoint.
• Over the limit returns 429 with {"error":"rate_limited"}.
• Invalid input returns 400 with {"error":"invalid_domain"}.

Versioning

The version is carried in the path. This page documents the /v1/ response as it stands today; a client that depends on a particular field should check it against a live response.
