Build an OpenAI-Style Paywall in FastAPI! 🔥 Redis + SQLite + Docker Full Demo with Real-Time Testing
💥 Ever wondered how OpenAI, Stripe, or Notion protect their APIs from abuse and still make money?
This video takes you behind the scenes of a production-grade FastAPI Paywall System — featuring rate limiting, API key tiers, Redis counters, SQLite usage tracking, and simulated billing — all running in Docker.
You’ll learn how to:
✅ Use FastAPI + Redis to enforce real-time rate limits per user and per endpoint
✅ Track usage and monthly quotas in SQLite (your mini billing system)
✅ Test with real curl commands, debug via /debug/redis and /debug/sqlite, and visualize limits in action
✅ Scale the same design to Kubernetes + Postgres + Redis Cluster for real SaaS environments
💡 Whether you’re building a startup, SaaS product, or learning backend architecture — this project teaches how to make your API secure, monetizable, and future-proof.
🧠 Topics Covered:
FastAPI Rate Limiting Middleware
OpenAI-style API Paywall Architecture
Redis for Real-Time Enforcement
SQLite for Persistent Quotas
API Key Authentication
