Using the x402 fetch client with a funded Base mainnet wallet.

import { wrapFetchWithPayment } from "x402-fetch"
import { privateKeyToAccount } from "viem/accounts"

const account = privateKeyToAccount(process.env.PRIVATE_KEY)
const fetchWithPay = wrapFetchWithPayment(fetch, account)

const res = await fetchWithPay("https://v0-x402-endpoint-creation.vercel.app/api/insight?topic=defi")
