API

Overview

This project contains the API source code that is hosted on a different server.

The complete REST API is documented below. All endpoints return JSON responses and validate input using Marshmallow schemas.

Health Check:

GET /health → {"status": "ok"}

Main Endpoints:

/buildings - Building management
/rooms - Room availability and filtering
/classes - Class scheduling
