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

Score up to 25 company or contact records against an ideal customer profile: 0-10 fit score, qualified / review / disqualified verdict, reason label. Calibrated on 240 labelled leads: 0.879 accuracy, and no qualified lead ever disqualified or vice versa. Catches competitor name variants and subsidiaries of excluded accounts that string matching misses. Uncertainty widens the net: sparse records, unnamed contacts and low-confidence calls go to review, never to disqualified.

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/38715.json for the price and payment options.
Pay. Call GET https://x402-production-0f93.up.railway.app/v1/score-leads. 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.
