Example 1: what is an api

An application program interface (API) is a set of routines, protocols, and
tools for building software applications.

Basically, an API specifies how software components should interact.
Additionally, APIs are used when programming graphical user interface (GUI)
components.

A good API makes it easier to develop a program by providing all the
building blocks. A programmer then puts the blocks together.

Example 2: what is an api

An application programming interface (API) is a computing interface which
defines interactions between multiple software intermediaries.

the data formats that should be used, the conventions to follow, etc.
