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://tfgmq-38-190-144-122.run.pinggy-free.link/api/x402-payment-challenge-conformance", { method: "GET" });
console.log(await res.json());
