Mirrored from Coinbase's public x402 Bazaar. The description is the provider's own text and has not been reviewed here; the payment requirements are copied as published.

What it does

Your own settled calls in the shape a finance system posts: one row per payment with what was bought, the amount settled, the quoted ceiling where one applied, and the evidence - settlement transaction, sha256 of the bytes delivered, and the on-chain attestation id where one exists. Keyed to the wallet that pays for the call, so nobody can read another wallet's payables; no account, no export request, no support ticket. Requires an EIP-3009 payment (USDC on Base, Polygon, or Arbitrum).

Use with an agent

Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
Inspect. Fetch /resources/28092.json for the price and payment options.
Pay. Call GET https://agent402.tools/api/receipts. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, Polygon, Arbitrum One, eip155:143, Avalanche, eip155:1329, Optimism, eip155:4663, eip155:42220, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
