Deep Dive
An Application Programming Interface (API) is a set of defined rules, protocols, and tools that allows different software applications to communicate and interact with each other. It acts as an intermediary, specifying how one software component should request functionality from another. Essentially, an API defines the methods and data formats that applications can use to send requests and receive responses, enabling seamless integration and data exchange without requiring developers to understand the internal workings of the interacting system.
