What it does

Spot price: the on-chain DEX price for SOL, BTC or ETH, the median of deep USDC pools on Solana, Ethereum and Base read from chain state, and the pools that served it. Use when you need to answer: What is the spot price, without picking a venue? Any other symbol answers 400 with the supported list and is never billed.

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/29684.json for the price and payment options.
  3. Pay. Call GET https://x402.ochinimus.app/api/price. 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 Solana, Base, Polygon, Arbitrum One, eip155:5042, algorand:wGHE2Pwdvd7S12BL5FaOP20EGYesN73ktiC1qzkkit8=, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
