Purpose-built for API monetization
Stripe, Kong, and Apigee are aircraft carriers. If you just need to charge for API calls, PayFence is the speedboat — 3 lines to start, enterprise controls when you're ready.

Two ways to integrate
Choose based on your architecture. Switch anytime.
Reverse Proxy
No changes to your API code. Redirect traffic through PayFence. We validate tokens, enforce quotas, and forward requests to your origin. ~35ms added latency. Runs on AWS.
Middleware
Add PayFence validation inside your server. Keep your domain and full control over requests. ~8ms per check. Runs in YOUR infrastructure.
What if PayFence goes down? Middleware runs inside your server — no external dependency. Proxy runs on AWS with 99.9% uptime. Both can be configured to fail-open, so your API stays accessible.
