Deep audit of an x402/ACP seller before trusting it: give a seller wallet or domain and get a full report — on-chain settlement reputation (settlements, unique counterparties, wash-trade/sybil, OFAC), the seller's advertised endpoints (from its /.well-known/x402.json), on-chain liveness, web reputation and red flags — fused into a TRUSTED/CAUTION/AVOID verdict with a signed, offline-verifiable receipt. Deeper than a pass/fail badge: the full seller due-diligence dossier for agentic payments.
