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

Base coin price mini-endpoint for major tokens only. Returns spot prices and 24h stats for well-known tickers like btc, solana, eth, xmr, ltc and other large-cap coins, never microcaps. Pass an optional ticker to get a single-coin 24h snapshot with price, symbol, changeRate, changePrice, high and low, or omit ticker to receive a compact basket of top tokens in a fixed order. Cost: 0.001 USDC per request.

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/33472.json for the price and payment options.
Pay. Call GET https://x402factory.ai/base/coinprice. 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.
