Agent402 Site Audit Discovery
Free, static product discovery for two existing x402 products on eip155:8453: the 5.00 USDC AI Discovery Site Audit and the 1.00 USDC Verified URL Evidence Snapshot. Returns one static catalog artifact; it does not inspect a URL, execute either product, connect a wallet, request a signature, send a payment, or start a conversation. Free site-audit eligibility: POST https://agent402.dev/site-release-audit/eligibility. Exact paid resources: POST https://agent402.dev/site-release-audit and GET https://agent402.dev/url-evidence.
AgentCard object — a capabilities object, a declared protocolVersion, and a well-formed skills array.
An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.
