Validate Requests with Pydantic
Reject malformed input before it reaches the model.
Garbage In, Garbage Out
If a client sends the wrong fields or types, your model gets nonsense. You want to reject bad input before it ever reaches the model. 🛡️
Meet Pydantic
FastAPI uses Pydantic to validate requests. You describe the shape of the data with a Python class, and validation happens for free.
