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

Wallet-risk check before paying any wallet: OFAC sanctions screening, whether it's a monitored x402 seller's payout wallet and how long it's been stable, recent unconfirmed payout-wallet switches to it (possible hijack), seller declarations, x402 payment history, and on-chain intelligence (first funder, one step back, wallet age and activity). Add compare=<other wallet> for same-owner evidence and a 0-1 confidence. Verdict: clear, caution, or block.

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/42081.json for the price and payment options.
Pay. Call GET https://lumierepaycheck.org/v1/wallet-risk. 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.
