Call it

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

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(process.env.EVM_PRIVATE_KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agentsvc.io/api/v1/proxy/useragent-parse", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({"user_agent":"Mozilla/5.0 (compatible; GPTBot/1.2; +https://openai.com/gptbot)"}),
});
const { data, payment } = await res.json();  // payment.transaction = on-chain receipt
