How is an API different from a web application?
There you have it: an API is an interface that allows you to build on the data and functionality of another application, while a web service is a network-based resource that fulfills a specific task. Yes, there’s overlap between the two: all web services are APIs, but not all APIs are web services.
Why do we use API?
APIs are needed to bring applications together in order to perform a designed function built around sharing data and executing pre-defined processes. They work as the middle man, allowing developers to build new programmatic interactions between the various applications people and businesses use on a daily basis.

What language is API written in?
Developers can use almost any modern programming language (like JavaScript, Ruby, Python, or Java) for their own API coding. Most programming languages already come with the necessary software to interact with web APIs, but developers typically install additional packages, or code, for convenience and flexibility.

more complicated API, request and response concepts are mixed together. lacks streaming, whole response is going to buffer in memory, not available for binary data.
