Payment challenge
HTTP 402, accepts entries, amount, asset, network, payTo, resource, and scheme.
Free provider check · no settlement
Check Coinbase Bazaar readiness before agents pay.
A Bazaar listing is more than a directory entry. Agents need a real HTTP 402 challenge, structured payment terms, discoverable schemas, consistent price and network metadata, and an operator-controlled activation step.

Observed public catalog visibility
The public catalog sample runs with the check.
Need help after the free check?
For one endpoint, Ontario offers a $199 one-time review covering the public payment challenge, Bazaar metadata, manifest/OpenAPI/MCP parity, and a copy-ready activation checklist.
You keep control of wallets and settlement. There is no placement, ranking, traffic, safety, or revenue guarantee.
What the check covers
Discovery contract
x402 manifest, Bazaar-style metadata, input/output schema evidence, freshness, and OpenAPI.
Provider activation
A clear operator checklist for testnet or controlled settlement, followed by external catalog verification.
What it does not prove
This free check does not make an endpoint appear in Coinbase Bazaar. Coinbase documents that Bazaar cataloging follows a successful settlement through the CDP Facilitator for a Bazaar-enabled route. Ontario does not perform that settlement, request private keys, verify external placement, or guarantee safety, traffic, ranking, revenue, or future behavior.
