Getting Started

Monetize your API for AI agents in under 5 minutes. AgentGate wraps your existing endpoints with x402 payment protection — agents discover, pay, and call your API automatically.

1Install

npx @dkerpal/agent-gate init

The CLI auto-detects your framework (Express, Hono, or Next.js), prompts for your wallet address, registers you on the marketplace, and generates a .agentgate.json config file.

2Add the Middleware

server.ts

import express from 'express';
import { agentgate } from '@agent-gate/middleware/express';

const app = express();

// Reads config from .agentgate.json
app.use(agentgate());

// Your routes — now payment-protected
app.get('/api/data', (req, res) => {
  res.json({ result: 'your data here' });
});

app.listen(3000);

3Deploy & Earn

Deploy your app as usual. AgentGate handles everything:
