🚀 One-Command Deploy

💰 Flexible Pricing

{
  "pricing": {
    "routes": {
      "GET /api/free/*": "free",
      "GET /api/basic/*": "$0.001",
      "GET /api/premium/*": "$0.01"
    }
  }
}

🔍 AI Agent Discovery

Your API is automatically discoverable by AI agents:

// AI agents can find your API
const apis = await discover({
  category: "weather",
  maxPrice: "$0.01"
});

📊 Built-in Dashboard

Monitor revenue, usage, and analytics in real-time.

Quick Start

1. Create Config File

Create x402.config.json:

{
  "name": "my-paid-api",
  "payment": {
    "wallet": "0xYourWalletAddress",
    "network": "eip155:42161"
  },
  "pricing": {
    "routes": {
      "GET /api/*": "$0.001"
    }
  }
}

2. Wrap Your API

import express from "express";
import { wrapWithX402 } from "@nirholas/x402-deploy/gateway";

const app = express();

app.get("/api/data", (req, res) => {
  res.json({ data: "premium content" });
});

// Add x402 payment layer
const wrappedApp = wrapWithX402(app);

wrappedApp.listen(3000);

3. Deploy
