CounterpartyCheck by AgentGate

Pre-payment counterparty check for agents: before paying or approving an EVM (Base, Ethereum, Polygon, Arbitrum) or Solana address, get ok / caution / block with reasons. Screens OFAC SDN and ScamSniffer scam lists, x402 Bazaar payee directory and known labels, and reads the address on-chain (wallet, contract, token contract, Safe, EIP-7702 delegation, activity, USDC balance).

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://api.youraitools.co/counterpartycheck/v1/lite", { method: "GET" });
console.log(await res.json());
