Client Example: x402-fetch

Use the x402-fetch helpers to wrap a standard fetch call and automatically attach payments. This script loads configuration from .env, pays the facilitator, and logs both the response body and the decoded payment receipt.

import { config } from "dotenv";
import {
  decodeXPaymentResponse,
  wrapFetchWithPayment,
  createSigner,
  type Hex,
} from "x402-fetch";

config();

const privateKey = process.env.PRIVATE_KEY as Hex | string;
const baseURL = process.env.RESOURCE_SERVER_URL as string; // e.g. https://example.com
const endpointPath = process.env.ENDPOINT_PATH as string; // e.g. /weather
const url = `${baseURL}${endpointPath}`; // e.g. https://example.com/weather

if (!baseURL || !privateKey || !endpointPath) {
  console.error("Missing required environment variables");
  process.exit(1);
}

/**

  const fetchWithPayment = wrapFetchWithPayment(fetch, signer);
