  • check_counterpartyIs it safe to pay this address?read-only

    Pre-payment counterparty check: before paying, approving or interacting with an EVM (Base, Ethereum, Polygon, Arbitrum One) or Solana address, get ok / caution / block. Free preview tier: verdict, confidence, address kind and flag counts. The paid x402 endpoints /v1/lite ($0.005), /v1/quick ($0.015) and /v1/full ($0.05) add the reasons and evidence (OFAC SDN, scam lists, x402 directory, verification, deployer, names, cross-chain, age, exposure). Informational safety check, not legal or financial advice.
