Building an API for a Model (Flask / FastAPI)

Summary

Wrapping a trained model in a lightweight web API so other applications can send it data and get predictions back — FastAPI is the modern, faster-growing choice with built-in data validation.

• 1Build a simple FastAPI endpoint that loads a model and returns a prediction.
• 2Test your API locally with a sample request using a tool like curl or Postman.
• 3Learn to validate incoming request data before passing it to the model.
