FastAPI Web APIs with Python

Build lightning-fast web APIs with modern Python tools.

FastAPI Web APIs with Python is a practical guide to building and deploying scalable, high-performance RESTful services using FastAPI, the modern web framework that’s quickly becoming a favorite among Python developers. Whether you're creating backend services, microservices, or full-featured APIs for web and mobile apps, this book shows you how to build clean, efficient code with FastAPI’s intuitive design.

You’ll learn how to:

• Set up FastAPI projects step by step

• Design RESTful endpoints with path and query parameters

• Handle requests and responses with Pydantic models

• Implement validation, error handling, and dependency injection

• Connect your APIs to databases using SQLAlchemy or async ORMs

• Add user authentication with OAuth2 and JWT tokens

• Test your APIs with built-in tools and pytest

• Create interactive docs automatically with Swagger and ReDoc

• Deploy FastAPI apps using Uvicorn, Docker, and cloud platforms

With clear examples and complete code snippets, you’ll go from zero to deployment—without the complexity of older frameworks.

Whether you’re building APIs for internal tools, public services, or client applications, FastAPI Web APIs with Python gives you everything you need to write production-ready web services that are easy to maintain and fast to run.
