X402 Monetize

Creates paid API endpoints using the x402 micropayment protocol. Wraps existing Zo skills and tools behind per-request payment walls. Each call costs $0.001–...

Create paid API endpoints that earn micropayments every time they're called.

What This Does

1. Wrap any Python script or Zo tool as an HTTP API endpoint
2. Add x402 payment middleware (client pays per-call via USDC on Base)
3. Register the endpoint as a Zo user service on port 4020
4. The endpoint runs 24/7 and deposits earnings automatically

Quick Start

cd /home/workspace/MoneyMachine/x402_server
node index.js

Endpoints Included

Endpoint	Price	Description
/api/signals/:ticker	$0.01	Options trading signal (bull/bear/neutral)
/api/whale/:ticker	$0.01	Whale flow alert (size, direction, conviction)
/api/wave/:ticker	$0.01	Elliott Wave count + Fibonacci levels
/api/maxpain/:ticker	$0.005	Max pain level + strike wall zones
/api/backtest	$0.05	Run options strategy backtest
/api/services	free	List all paid endpoints

Adding a New Paid Endpoint

const { paymentMiddleware } = require('@x402/express');

// Add to index.js:
app.get('/api/my-endpoint', paymentMiddleware(), async (req, res) => {
  // Your logic here
  res.json({ result: 'paid data', price: '$0.01' });
});

Payment Flow

1. Client requests /api/signals/AAPL
2. Server returns 402 Payment Required with payment details
3. Client pays USDC to facilitator
4. Client retries with payment proof
5. Server returns data
