CDP publishes machine-readable x402 resource discovery
The Bazaar-style discovery API is how agents find payable HTTP resources.
Coinbase Developer Platform exposes x402 discovery endpoints, including resource listings and merchant-by-payTo queries. These indexes are observations of listed resources and optional quality fields such as recent calls and unique payers. They are not Foundry revenue and not proof of independent demand for any one seller.
Why it matters
Discovery is the top of the machine funnel. Index freshness, schema validity and payer fields are zFinia’s proprietary join surface.
