Live Entity Verification API

A human read this entry. That is the one thing true of everything on the list. Beyond that: the endpoint answered an x402 request when we knocked it, on the date shown. That date is the claim — not a word, a date. None of it is a delivery test. We have not paid for this and graded what came back, so read it as "we checked what is stated above," never as "this is worth the money."

Cross-signal Bayesian corroboration of entity existence: fuses WHOIS, Certificate Transparency, Wayback Machine, and DNS operational maturity into a calibrated hallucination verdict with a confidence score. $0.01-$0.05 USDC on Base Sepolia (testnet) via x402, tiered per route. Example: `POST /verify-entity-existence-cross-signal {"domain":"example.com","entity_name":"Example Corp"}`.
