# FastAPI Expert

Stand up a Python web API with typed models and auth

## What this does

You need a Python service that other software can call, and you would rather not hand-roll the request handling, the data checks, and the login part yourself. This helps you write those endpoints, describe the shape of the data going in and out, wire up the database, and produce documentation of the API for whoever uses it.

### Top 3 things it does for you

- Build REST endpoints in Python
- Add login and token-based authentication
- Set up database calls that do not block

## About FastAPI Expert

This is for building web APIs in Python with FastAPI and Pydantic V2. It covers creating REST endpoints and defining the Pydantic models that describe your request and response data.

It also handles the parts that usually come next: authentication flows including JWT, async SQLAlchemy for database operations, and WebSocket endpoints when a connection needs to stay open.

Reach for it when someone says FastAPI, Pydantic, async Python, or asks for OpenAPI and Swagger documentation of what they have built.

## Questions

### Is FastAPI Expert safe to install?

AIR scanned this exact version of FastAPI Expert and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 1508683aad11, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/fastapi-expert.
