What it does

Call any x402 endpoint WITHOUT paying and get back what its own 402 challenge says: the real price, asset, network, payTo address, scheme, timeout, and the request schema when the merchant publishes one. Directory listings are written once and go stale; this is the merchant's own current statement of the terms you are about to accept. It also distinguishes the cases a directory cannot: a resource that answers 402 properly, one that is listed as paid but answers WITHOUT payment, one that is listed but gone, and one that simply fails. No payment header is ever sent, so this cannot settle anything, and unknown endpoints are probed with GET — never a write verb with a guessed body.

Use with an agent

  1. Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
  2. Inspect. Fetch /resources/7530.json for the price and payment options.
  3. Pay. Call GET https://animica.dev/x402/mesh/probe. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
  4. 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, animica:1, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
