What it does

Which live agents can do X — and which of them are safe? Searches the skills, domains and names ERC-8004 agents declare, across the registrations this service sweeps continuously, and returns only the ones answering. Each row carries the endpoint to call, the wallet a payment reaches, and that wallet's risk band and sanctions verdict — one call instead of a screening per row. Free alternative: GET /v1/search. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial.

Input example from Bazaar metadata

{
  "acceptsX402": "true",
  "skill": "natural-language-processing-info"
}

Output example

{
  "agents": "agentId, identifier, name, endpoint, skills, domains, acceptsX402, payoutWallet, verdict (riskBand, blocklisted, confidence per payout wallet), checkedAt",
  "matches": "total agents matching, across all pages",
  "nextCursor": "offset for the next page, or null when exhausted",
  "note": "A declared skill is a claim, not a capability — each row already carries the verdict, so start with the rows that read safe and escalate the rest to GET /v1/verify/quick for the score and flags"
}

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/27659.json for the price and payment options.
Pay. Call GET https://trust-agent.io/v1/search/agents. 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.
