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.AGENT_WALLET_PRIVATE_KEY as Hex | string;
const agentUrl = process.env.AGENT_URL as string; // e.g. https://agent.example.com
const endpointPath = process.env.ENDPOINT_PATH as string; // e.g. /entrypoints/echo/invoke
const url = `${agentUrl}${endpointPath}`;

if (!agentUrl || !privateKey || !endpointPath) {
  console.error("Missing required environment variables");
  console.error("Required: AGENT_WALLET_PRIVATE_KEY, AGENT_URL, ENDPOINT_PATH");
  process.exit(1);
}

/**
 * Demonstrates paying for a protected resource using x402-fetch.
 *
 * Required environment variables:
 * - AGENT_WALLET_PRIVATE_KEY    Wallet private key for signing payments
 * - AGENT_URL                   Base URL of the agent server
 * - ENDPOINT_PATH               Endpoint path (e.g. /entrypoints/echo/invoke)

  const fetchWithPayment = wrapFetchWithPayment(fetch, signer);

  const response = await fetchWithPayment(url, { method: "GET" });
