Check a Base or BNB Chain (?chain=bsc) address before you pay it: a verdict label pay / hold / unknown with a human text (Pay, Hold, Inactive, No track record or Couldn't check) and the one reason, such as active with real counterparties or a high-severity flag named. Under it, the evidence: every flag with its source, what was not assessed, and the EAS attestation if one exists. On-chain behavior

Call it from code

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.chainward.ai/api/risk/counterparty", { method: "GET" });
console.log(await res.json());
