whats an API , can you make one on spot

Question

Accepted Answer

An API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate with each other.

APIs define the methods and data formats that applications can use to request and exchange information.
They enable developers to access the functionality of other software components or services without having to understand their internal workings.
APIs can be used to retrieve data from a remote server, send data to a server, or perform specific actions.
Examples of APIs include the Google Maps API, Twitter API, and Facebook Graph API.
