## 🏗️ How it Works (The Toll Booth Analogy)
Think of **MachinePay** as a **toll booth for the internet**.
Instead of reaching a website directly, requests first pass through the proxy:
1. **🔗 You send a request** → try to access a resource
2. **🚦 MachinePay proxy intercepts** → checks if payment is included
3. **💳 Payment verified** → confirmed via the x402 protocol
4. **📡 MachinePay proxy forwards request** → to the real website
5. **🖥️ Website responds** → returns content
6. **📬 MachinePay proxy delivers to you** → completing the paid access loop
✅ Result: Websites instantly monetize access while staying secure and compliant.
