The modern web is quite literally built on APIs. I do not mean this in a philosophical sense or to point toward an idea like “API First” design. However, the fundamental way that data is passed back and forth on the web is structured around the concept of an API. As the internet and web grew, the ability to cheaply and easily pass text and binary data over HTTP became easier than developing network transfers from scratch. Point your application at a URL and have it parse the response.
