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

Use this when you need the same stock from every issuer on Base in one call: send a ticker (NVDA, AAPL, TSLA) and get, per issuer — ST0x (wtNVDA) and Coinbase tokenized stocks (NVDAc, B20) — the genuine contract verified against the issuer's own registry, live price, premium/discount vs the real share in bps, pool depth and 24h volume, the ST0x-vs-Coinbase spread, any direct cross-issuer pool, and every impostor token using the same symbol. xStocks flagged as not on Base.

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/41842.json for the price and payment options.
Pay. Call GET https://x402-accelerometer-feed.fly.dev/tokenized-equities/same-stock/:ticker. 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, Solana, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
