Fetch Todos API in FastAPI | Read Data from PostgreSQL Database

Описание: Welcome to another video of the FastAPI Series! 🌙

In this session, we’re building a Fetch (GET) Todos API in FastAPI and learning how to read data from a PostgreSQL database using SQLAlchemy Async. 📥🐘

This video completes the Read part of the CRUD workflow and shows how real‑world APIs return data efficiently.

By the end of this lesson, you’ll understand:
✅ How to create a GET API in FastAPI
✅ How to fetch multiple records from PostgreSQL
✅ How to use SQLAlchemy AsyncSession to read data
✅ How select() and scalars().all() work
✅ How to use response_model to control API output
✅ How to convert ORM models into Pydantic models
✅ How to apply rate limiting on read APIs
✅ How to return clean and structured API responses

With hands‑on coding, clear explanations, and real database demos, you’ll gain the confidence to build production‑ready read APIs using FastAPI + PostgreSQL. 🚀
