What it does

Is this address safe to pay? Screen a wallet address before you pay or send funds to it: an OFAC SDN sanctions check of the address plus address reputation (drainer, phishing, mixer, money laundering) for EVM and Solana. Returns one verdict to branch on (allow, review, or block) with a 0-100 risk score and per-signal evidence. AML / KYT counterparty check for x402 payments. $0.02 USDC.

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/27184.json for the price and payment options.
Pay. Call GET https://api.anchor-x402.com/v1/screen. 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, eip155:5042, Polygon, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
