Think of MachinePay as a toll booth for the internet.
Instead of reaching a website directly, requests first pass through the proxy:
- 🔗 You send a request → try to access a resource
- 🚦 MachinePay proxy intercepts → checks if payment is included
- 💳 Payment verified → confirmed via the x402 protocol
- 📡 MachinePay proxy forwards request → to the real website
- 🖥️ Website responds → returns content
- 📬 MachinePay proxy delivers to you → completing the paid access loop
✅ Result: Websites instantly monetize access while staying secure and compliant.
