# Building NexusSaaS: A Monetized AI Micro-API Gateway
For Week 2 of the Hacktoberfest 2026 DEV Challenge, I built NexusSaaS —a lightweight, monetization-ready micro-API gateway using FastAPI that validates API subscription keys and tracks token usage for a developer-focused tool.
An asynchronous FastAPI backend featuring API key authentication headers, tiered access control, and usage metering designed to be packaged as a commercial developer tool.
Building modular, API-first microservices allows developers to easily prototype commercial products, test subscription mechanics, and manage secure header authentication locally before deploying to cloud infrastructure.
