payable

Deterministic public-posture audit of a domain: A/AAAA/MX/NS/TXT records, SPF, TLS certificate issuer, validity window and days until expiry, plus whether robots.txt and security.txt are published (with hashes). One call instead of a dozen lookups. No model involved — every field is read directly from DNS or the TLS handshake.

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
