Old Colony Web Agent Services

For $0.002, test a real x402 v2 exact USDC payment on Base and receive an intentionally simple JSON handler result. The successful final HTTP response and PAYMENT-RESPONSE header (not the body alone) are evidence of the x402 settlement flow. No refund, wallet-balance check, blockchain-finality guarantee, variable tip, data lookup or downstream action. Do not retry an ambiguous charge blindly.

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://api.oldcolonyweb.com/v1/payment/self-test", { method: "POST" });
console.log(await res.json());
