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://7mavs5vu7ggbhtxvbavdgs26qa0cbawg.lambda-url.us-east-1.on.aws/paid/validation-attest", { method: "POST" });
console.log(await res.json());
