What problem does it solve?

Developers often need to decide between FastAPI and Flask for building production-grade APIs and to implement robust patterns for validation, authentication, and async behavior. This skill provides structured guidance, practical patterns, and best practices to deliver robust REST APIs using Python.

Core Features & Use Cases

• Framework selection guidance between FastAPI and Flask for REST APIs.
• Dependency injection, Pydantic validation, and request handling patterns.
• Authentication strategies (JWT, OAuth2, API keys) and async endpoint patterns for scalable services.
• Use cases include small services, microservices, and data-driven APIs with validation and security requirements.

Quick Start

Create a small FastAPI project with a simple model and route to verify functionality.
