Free Library API
The Library API is a classic project for beginners. Practice building a catalog system to track books, authors, ISBNs, and whether copies are currently checked out.
What is a REST API?
An API (Application Programming Interface) allows two software programs to communicate. A REST API uses standard HTTP requests like GET (to read data), POST (to create data), PUT (to update), and DELETE (to remove).
When you send a request to our https://techidea.online/api/v1/library endpoint, our server responds with a JSON (JavaScript Object Notation) array containing data. You can then display this data in your frontend React, Next.js, or mobile applications.
