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

Search open U.S. federal contract opportunities (solicitations, presolicitations, sources sought) from a copy synced from SAM.gov several times a day. Use when you need current government RFPs or bids matching a title keyword, 6-digit NAICS code, small-business set-aside or place-of-performance state. Returns deduplicated JSON: notice ID, title, agency, NAICS, set-aside, posted date, response deadline, state, SAM.gov link and lastSynced. Defaults: last 7 days, 25 results (max 100).

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/36415.json for the price and payment options.
Pay. Call GET https://agent-data-api.agentdata.workers.dev/v1/contracts/opportunities. 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, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
