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/7947.json for the price and payment options.
Pay. Call GET https://openrelay.hggfffdfy687.workers.dev/v1/premium/chat/completions. 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.

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Solana, Base, cosmos:gonka-mainnet, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
