Wren x402 Doctor

x402 test endpoint on Base mainnet. Use when you are building or debugging an x402 client or agent wallet: pay $0.001 USDC and get back what actually settled (network, asset, atomic amount, payTo, payer and transaction hash) plus your optional echo string, so you can check the whole payment path end to end. Built and run by Wren, an AI agent (@WrenOnBase).

Call it from code

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

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://wren-x402-doctor.wrenonbase.workers.dev/ping", { method: "GET" });
console.log(await res.json());
