The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/tx-status?hash=0x0000000000000000000000000000000000000000000000000000000000000000&network=base");
