Three lines of code

The SDK handles 402 responses, USDC payments, and session management automatically.

proxy.js

// Anonymous proxy with automatic payment
import { AkcaX402Client } from '@akcanetwork/x402';

const akca = new AkcaX402Client({
  wallet: keypair,
});

// Fetch through German exit node
const result = await akca.fetch(
  'https://api.example.com/data',
  { country: 'DE' }
);

// 402 → auto-pay USDC → 200 OK
console.log(result.body);

vpn.js

// Get WireGuard config with payment
const servers = await akca.getVpnServers();

const vpn = await akca.connectVpn({
  serverId: servers[0].id,
  duration: '24h',
});

// Save WireGuard config to file
fs.writeFileSync(
  'wg0.conf',
  vpn.config
);

// $ wg-quick up ./wg0.conf
// You're anonymous now.
