How does the API work?

API (Application Programming Interface) is a set of rules and protocols that allows different programs to interact with each other. In the context of web development, APIs typically operate on a client-server model: the client sends requests (for example, via HTTP), the server processes them and returns responses.

Example: REST API uses HTTP methods (GET, POST, PUT, DELETE) to work with resources. For instance, a client can send a GET request to retrieve a list of users, and the server will return data in JSON format.

Thus, an API serves as a bridge for exchanging data and functionality between applications.
