ChainWard wallet lookup

Fast wallet lookup on Base or BNB Chain (?chain=bsc): OFAC sanctions, first seen, last active, sent transactions, native and USDC balances, and the first funder (sanctioned, exchange or hub, or funder of many wallets). Verdict hold / review / no_flags with one reason; a never-used Base address planted as an address-poisoning decoy gets hold; a payer that is a px402 privacy pool relayer gets review

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/wallet", { method: "GET" });
console.log(await res.json());
