Bazaar Discovery

Every paid Apiosk route already returns a self-describing 402: the payment requirement carries the route’s discovery metadata. After a route’s first successful settlement, that metadata is indexed into Coinbase’s CDP x402 Bazaar, the public discovery layer for x402 resources. Agents that browse the Bazaar can then find and price Apiosk endpoints with no prior knowledge of them.

​
What gets indexed

  • Standalone APIs only. Published listings (listing_type = api) that have settled at least one paid call are indexed under the platform payout address.
  • Connect skills are never indexed. Marketplace skills are private and reachable only via their charge_url (see /guides/connect-marketplace).

​
How a route gets there

You do not call a discovery API to register, indexing is a side effect of normal operation:
  1. Publish and verify a listing (see /guides/publishers).
  2. The route serves a self-describing 402 automatically.
  3. On the first settled call, the Bazaar indexes the resource. New routes appear within minutes.
Because indexing keys off the first settlement, a listing that has never taken a paid call will not yet appear in the Bazaar. Nothing else is required, good listing metadata (see /guides/listing-metadata) simply makes the indexed entry more useful to agents.
