How to pay with x402

Call an endpoint; receive 402 with PAYMENT-REQUIRED header (base64 JSON). Retry with PAYMENT-SIGNATURE header using any x402 client (@x402/fetch, @x402/axios, python x402).

1. 1

   Call the endpoint

   Send a normal HTTP request to any /v1/* route. No headers or keys needed.
2. 2

   Read the 402

   You get 402 Payment Required with a PAYMENT-REQUIRED header: base64 JSON with the price, asset, network and pay-to address.
3. 3

   Sign a USDC payment

   Your x402 client signs an exact-amount USDC transfer on Solana mainnet. The facilitator pays the network fee.
4. 4

   Retry and get data

   Repeat the request with PAYMENT-SIGNATURE. You get 200 OK, the JSON result and a PAYMENT-RESPONSE receipt.

import { wrapFetchWithPayment, x402Client } from "@x402/fetch";
import { registerExactSvmScheme } from "@x402/svm/exact/client";

const client = new x402Client();
registerExactSvmScheme(client, { signer }); // your Solana signer
const pay = wrapFetchWithPayment(fetch, client);

const res = await pay("https://scorptech.it.com/api/x402/v1/headers-audit?url=https%3A%2F%2Fexample.com");
console.log(await res.json());
