How to Get Listed in Coinbase Bazaar
A provider checklist for preparing an x402 endpoint for Coinbase Bazaar discovery without confusing metadata readiness with catalog placement.
Direct Answer
There is no separate manual registration step for a Bazaar-enabled route. A provider declares the current Bazaar discovery extension, returns a valid HTTP 402 challenge with matching payment and input/output metadata, and completes a successful settlement through the CDP Facilitator. Ontario's free checker validates the public preparation work; the provider must approve the settlement and verify the external catalog result.

Evidence Checklist
- Confirm the endpoint or service origin is reachable over HTTPS.
- Confirm unpaid paid-API calls fail closed with intentional HTTP 402 metadata.
- Compare the manifest, OpenAPI schema, service profile, and report evidence.
Agent Workflow
- Open the canonical answer page for how to get listed in Coinbase Bazaar.
- Run the readiness API and save the report ID before payment.
- Call /api/agent/can-pay with the agent policy and max spend.
- Allow payment only when the report, manifest, and price metadata agree.
Machine Entry Points
Agents can use the JSON mirror, verification API, MCP manifest, x402 manifest, and buyer guide without scraping prose.

Why This Matters
Paid agent calls fail expensively when endpoint metadata is missing, payment challenge behavior is unclear, or the service cannot be integrated by a crawler. Ontario turns those checks into signed reports, historical monitoring, service profiles, and a can-pay decision agents can use before spending.
