Email Authentication Posture Check (SPF/DMARC/DKIM/MX)
https://ryan-default-sherman-pins.trycloudflare.com/posture-v1Overview
Per-call analysis of a domain's email authentication setup: parses the SPF policy (including +all/~all and the 10-lookup PermError limit), the DMARC policy and rua reporting address, resolves common DKIM selectors, and lists MX records. Returns the policy records themselves, a list of specific defects and a 0-100 score. Use to check whether a domain can be spoofed or whether a partner's mail setup is sound. Call with ?domain=example.com. Paid per call over x402 in USDC on Base.
