Via direct x402 (advanced)Bring your own wallet

import { wrapFetchWithPayment } from "@x402/fetch";
import { createWalletClient, http } from "viem";
import { privateKeyToAccount } from "viem/accounts";
import { base } from "viem/chains";

const account = privateKeyToAccount("0xYOUR_PRIVATE_KEY");
const client = createWalletClient({ account, chain: base, transport: http() });
const x402Fetch = wrapFetchWithPayment(client);

const res = await x402Fetch("https://graph-advocate-production.up.railway.app", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ /* check provider docs for input */ }),
});
const data = await res.json();

Requires USDC on Base and gas on each call. The @x402/fetch client signs EIP-3009 transferWithAuthorization for each 402 response and retries.
