🧾 Project Prompt (Assignment)

Your team wants the same Users API in Python for an AI-focused stack.

Rebuild the Users CRUD API using FastAPI with strong typing and automatic docs.

Requirements

• Same endpoints as the Node.js version
• Pydantic models for request + response
• Validation errors return friendly messages
• Add tests for success + failure cases
• Include a health check endpoint: GET /health

🛠 Tools (Tech Stack)

• Python
• FastAPI + Uvicorn
• Pydantic
• Pytest (plus httpx or FastAPI TestClient)

💡 Implementation Hints

• Separate layers: api/ (routers) vs core/ (services) vs db/ (later)
• Use response_model to prevent leaking internal fields
• Keep “business rules” out of route handlers
• Add a consistent error handler (custom exceptions → HTTP responses)
