What is an API?

An API, or “Application Programming Interface,” is a set of rules that lets one software application talk to another (i.e., send and receive data).

For example, consider the weather app on your phone. This app is not directly connected to a weather station; instead, it collects data from a weather database maintained by a third party—and an API is what lets your weather app exchange information with this database.

When creating an API, documentation is paramount. QuillBot’s free AI API Documentation Generator simplifies this process, saving you time and effort.
