Answers "Is it safe to send money to this address?" before an agent pays an x402 payTo, a vendor, a user or another agent, and "Who is behind this address?". Checks, on Base or Ethereum: whether the address is on the US Treasury OFAC SDN or Consolidated lists, and whether anything controlling it is (the owner of a contract, the owners of a Safe multisig, an EIP-7702 delegate, a proxy implementation); what it is (a person's wallet, smart wallet, Safe multisig, token contract, proxy or other contract); how many transactions it has sent; its ETH and USDC balances; and flags a never-used wallet or a token contract (sending funds to one usually loses them). Returns a verdict (high_risk, caution, no_flags), a 0-100 risk score and the reasons, with an explorer link. Read live from the chain; OFAC lists refreshed every 12 hours. A screening aid, not legal advice. You are only charged when a result is returned: invalid input (400) and upstream failures (4xx/5xx) are not settled. Costs $0.005 USDC per call via x402. Paid per call with x402 inside MCP (see the server instructions).
