Module 4: API Serving & FastAPI (The Restaurant Waiter)

📚 Module 4: API Serving & FastAPI

Course ID: OPS-604

To let others use your model, you need to “Serve” it through an API.

🏗️ Step 1: The Waiter (The “API”)

🧩 The Analogy: The Restaurant Flow

• The User (Customer) gives the API (Waiter) their Data (Order).
• The Waiter carries the order to the Model (Chef).
• The Chef processes the data and hands the Prediction back to the Waiter.

🏗️ Step 2: FastAPI

FastAPI is a Python library for building these “Waiters” incredibly quickly. It automatically builds a Menu (Swagger) for you!
