Learn FastAPI
FastAPI is a Python framework for building web APIs. It validates request data against declared types and generates API documentation automatically.
Why teams use it
- Type-driven validation catches malformed requests before your logic runs.
- Async support suits calling slow external services such as model APIs.
- Generated OpenAPI docs make the service easy for other teams to consume.
Where you will meet it
The orchestration layer of an AI feature — prompt assembly, retrieval, tool calls — is often a FastAPI service.
What to learn, and in what order
Work through these roughly in order. Jumping to the advanced list before the basics are solid is the most common way people get stuck.
Beginner
- First endpoint
- Request and response models
- Path and query parameters
Intermediate
- Dependency injection
- Async endpoints
- Error handling
- Streaming responses
Advanced
- Background work
- Deployment and containerisation
- Observability
