How do APIs work?

In general, Application Programming Interfaces are software tools that act as intermediaries, enabling communication and interaction between different software applications.

AI APIs are thus viewed as bridges between software and AI services, allowing you to access AI capabilities without building them from scratch. These APIs offer standardized interfaces that give seamless integration of AI functionalities into diverse projects.

For instance, when you use a music streaming app to locate a playlist, the app utilizes an API to send this request to the service, which then retrieves and delivers your playlist. Similarly, when you update your shipping address on an online store, the app communicates this change through an API to update the store's database.

An API transaction typically involves several key components: a request from the application for a specific operation, a response from the server after processing the request, endpoints, which are the specific locations where requests are sent, and responses are received, and methods that dictate the type of operation performed.
