# Bazaar Discovery

> How Apiosk gateway routes become discoverable to agents through Coinbase's CDP x402 Bazaar after their first settled payment.

# 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](/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](/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.

<Note>
  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](/guides/listing-metadata))
  simply makes the indexed entry more useful to agents.
