check_counterparty
Is it safe to pay this address?
Pre-payment counterparty check for an EVM (Base, Ethereum, Polygon, Arbitrum One) or Solana address: ok / caution / block with a confidence, from OFAC SDN and ScamSniffer screening, the x402 Bazaar payee directory, wallet vs contract vs token vs Safe, verification, names and cross-chain presence. Free preview by default (verdict, confidence, address kind, flag counts). With COUNTERPARTYCHECK_X402_PRIVATE_KEY set, returns the paid quick report (reasons, OFAC SDN and scam-list matches, x402 directory, verification, deployer, ENS / Basename, cross-chain presence) from https://api.youraitools.co/counterpartycheck/v1/quick, paying $0.015 USDC on Base per check over x402. Automated pre-payment due-diligence signals from public lists and on-chain data. Not legal, compliance or financial advice; "ok" means no known risk signal was found, not a guarantee.
