This is a brief introduction to commonly used apis
1, What is API
An application programming interface, or so-called API, is a computing interface that defines interactions between multiple software intermediaries. It defines the kinds of calls or requests that can be made, how to make them, the data formats that should be used, the conventions to follow, etc.
In short, API is where you can get data.
