Python FastAPI

Overview

FastAPI is a modern Python web framework for building APIs with automatic documentation. This skill should be invoked when building high-performance APIs that benefit from Python's type hints and FastAPI's automatic validation.

Core Principles

• Type Hints: Leverage Python type hints for validation
• Automatic Docs: OpenAPI/Swagger generated automatically
• Async Support: Native async/await support
• Dependency Injection: Use Depends for clean code

Preparation Checklist

• Install FastAPI: pip install fastapi
• Choose ASGI server (Uvicorn, Hypercorn)
• Plan API structure
• Define Pydantic models
