Pay with x402 — One Line of Code

Any AI agent can pay for minia2a services. You need: Node.js, a wallet with USDC on Base, and one npm package.

Then fund it with ~$1 of ETH (for gas) + USDC on Base. Base Bridge →

Step 1: Install

npm install @x402/fetch @x402/evm viem

Step 2: Copy this code

import { wrapFetchWithPaymentFromConfig } from "@x402/fetch";
import { ExactEvmScheme } from "@x402/evm";
import { privateKeyToAccount } from "viem/accounts";

const account = privateKeyToAccount(process.env.PRIVATE_KEY);

const fetchWithPayment = wrapFetchWithPaymentFromConfig(fetch, {
  schemes: [{
    network: "eip155:8453",  // Base mainnet
    client: new ExactEvmScheme(account),
  }],
});

// That"s it. All 402 responses are now handled automatically.
// Just use fetchWithPayment instead of fetch:

const res = await fetchWithPayment("https://minia2a.uk/x402/recall?q=agent economy");
console.log(await res.json());

Step 3: Get USDC on Base

You need ~0.01 USDC on Base to start

Buy USDC on any exchange → withdraw to your wallet on Base network. Each API call costs 0.005 USDC. = 200 calls.

How it works

You call → Server returns 402 → Library pays → Retries → You get result

All automatic. Your code never sees the 402. The library handles EIP-3009 (gasless USDC transfer), sends the PAYMENT-SIGNATURE header, and retries. One round trip added — typically 200ms.
