## What is an API?

An API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate with each other. It defines the methods and data formats that applications can use to request and exchange information. APIs enable the integration of different systems and services, facilitating the development of complex functionalities by leveraging existing components.
