x402.agentharbor.agency/domain-verify

Given a domain, tells whether it is a real, live and established business domain: DNS (A, MX, NS, SPF, DMARC, DNSSEC), registration from RDAP (registrar, created and expiry dates, age, status; never registrant contacts), the TLS certificate (valid, issuer, expiry) and the website (final URL, status, HSTS), with risk flags such as newly registered, no MX or invalid TLS. 'Does not exist' is an answer. Not charged if lookups fail.
