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

Crypto token price: live USD price, 24h change, total supply and FDV for any token, read onchain from DEX pools (Uniswap v3 on Ethereum, Base, Arbitrum, Polygon; Orca, Raydium, PumpSwap on Solana), so every number is verifiable. Pass token (ETH, BTC, SOL, PEPE... or contract/mint address), optional chain. Returns price, change, pools, depth, spread, confidence, block. 0.002 USDC/call; failed calls are free.

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/28411.json for the price and payment options.
Pay. Call GET https://x402-seller-pmlm.onrender.com/price. 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, Polygon, Arbitrum One, Solana, Avalanche, eip155:1329, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
