How to get an x402 endpoint listed and featured in the CDP Bazaar

To get an x402 endpoint listed and featured in the Coinbase CDP Bazaar, several steps must be followed. First, it's important to validate your endpoint before waiting. This can be done with a free check using the curl command, which requires no API key. The endpoint must pass the validation with a simulation.outcome of accepted.

Next, you need to ensure your endpoint is settled at least once every 30 days. If it goes 30 days without a settlement, it will be removed from both the catalog and search results. Additionally, the endpoint must continue to respond to 402 Payment Required requests in order to remain listed. The description of the endpoint should be kept at 500 characters or fewer.

To get featured in the Bazaar, your endpoint must meet certain criteria. It must have live x402 payments on mainnet, with at least 99% availability over 30 days and a priority above 99.5%. The endpoint must also pass a health probe and a validate call. It's crucial to provide agent-ready metadata, including a complete input schema, a description specifying when an agent should use the endpoint, pricing for per-call, supported networks, and documented error responses. The "when to use" sentence is often overlooked, but it's essential for successful listing.

Finally, it's important to understand the market. Of the 34,062 Bazaar endpoints, only 16,236 have at most one payer in 30 days. You can check listing history and payer counts for endpoints by using the Tanod MCP server's tools, such as get_endpoint_history and query_agent_index. Remember, the rules for the CDP x402 documentation can change, so it's essential to re-check the docs before relying on them.
