What is REST API? How do you understand it?

REST API (Representational State Transfer Application Programming Interface) is an architectural style for interaction between a client and a server over the HTTP protocol. The main idea of REST is to use standard HTTP methods (GET, POST, PUT, DELETE) to work with resources, which are represented as URLs.

REST API allows creating, reading, updating, and deleting data on the server, with data usually transmitted in JSON or XML format. This approach ensures simplicity, scalability, and component independence.

Example of a request to get a list of users:

GET /api/users HTTP/1.1
Host: example.com
Accept: application/json

The server response contains data in JSON format with information about users.
