Due-diligence scorecard for a single x402 resource before an agent pays it: when we first
Due-diligence scorecard for a single x402 resource before an agent pays it: when we first observed it in public catalogs (CDP Bazaar, Agentic.Market), how consistently it has stayed listed, when it appeared as a new listing, and its recent observation history — from our collector archive (~3x/day since 2026-07-06). Presence and persistence in public catalogs, not an endorsement. Deterministic; public-source data only; no internal transaction data. Pass resource=<full URL as listed>.
