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://x402-niche-briefs.fly.dev/v1/hs-tariff-section301-brief", { method: "GET" });
console.log(await res.json());
