Type-safe agents with validated structured output and dependency injection.

Overview

Pydantic AI brings the validation model that Python developers already use for API boundaries to agent output. Responses are parsed into typed models and validated before your code sees them, so a malformed tool argument fails at the boundary rather than three call frames later. Model-agnostic, with a FastAPI-shaped developer experience.

Why it's indexed

Closes the gap between a demo that parses JSON by hand and a service that validates at the edge.
