You can find the complete project and test files for this tutorial on GitHub if you’d like to follow along or extend the code further.
In this tutorial we are going to build a REST API using Python Flask. We will create a simple Flask application that serves a single endpoint, GET /items, which returns a list of items from a SQLite database.
This guide is written for beginners and will walk you through each step in a straightforward way. By the end, you will have a working API, a basic test file to verify the API, and a project structure that you can zip and upload to GitHub.
