paid-x402

Agent Intelligence — Profile Lookup

Runnable quickstart — Make your first paid call. This is the cheapest paid endpoint ($0.01 USDC on Base, settled via x402 / EIP-3009 transferWithAuthorization). See the curl, Python, and TypeScript tabs below for a copy-paste 402 -> pay -> 200 flow. The server pays gas; your wallet needs only >= $0.01 USDC on Base and NO ETH. Payment settles to the Safe treasury 0xaCd134d2AAd0b868EDb395F7d151864188caaF1a — never an EOA signer. Reference implementation: smartcontractauditpro/x402_smoke.py.

Full enriched profile for any ERC-8004 agent. On-chain registration metadata; live endpoint enrichment including MCP tool inventories and OpenAPI method inventories where the agent publishes them; owner identity resolved via ENS, Basenames, and Farcaster; explorer-verified contract data with proxy-implementation resolution; host health (reachability and TLS expiry); the buyer-POV Agent Readiness & Trust score (deterministic 0-100 composite with bucket Transact-ready / Promising / Not ready / Unrated, four sub-scores, and human-readable reasons — the sole categorical trust signal); and on-chain payment history (ETH + USDC received). Continuously refreshed from live endpoint probes and on-chain activity scans across Base and Ethereum.

Payment (x402):

  • base: 0.01 USDC (EIP-3009)
  • ethereum: 0.01 USDC (EIP-3009)

The 200 response body carries paid-gated intel; field-level schemas are intentionally not published. See the 402 preview block for the buyer-visible teaser.
