CounterpartyCheck lite: pre-payment address check
https://api.youraitools.co/counterpartycheck/v1/liteOverview
Before your agent pays, approves or interacts with an EVM or Solana address, get ok / caution / block with reasons, evidence and a confidence level. Lite ($0.005): verdict, OFAC SDN and ScamSniffer scam-list matches, and on-chain kind (wallet, contract, EIP-7702 delegated, token contract, Safe). Safety check only, not legal, compliance or financial advice: 'ok' means no known risk signal was found, not that the counterparty is trustworthy. Lists are snapshots. USDC on Base, Polygon, Arbitrum One or Solana via x402, or prepaid YourAITools credit keys. Built by YourAITools (youraitools.co).
