Which of the following is true about APIs?

APIs, or Application Programming Interfaces, play a crucial role in the software ecosystem by facilitating communication between different software applications. They provide a set of rules and protocols that govern how different software components should interact with each other. This allows developers to integrate various services and functionalities without needing to understand the inner workings of each component, promoting efficiency and flexibility in software development.

By serving as intermediaries, APIs enable applications to exchange data and request certain functionalities, fostering interoperability among different systems. This capability is essential in today's technology landscape, where applications often need to work together seamlessly, from web-based platforms to mobile applications and beyond. Thus, the correct answer highlights a fundamental aspect of APIs in modern software development.
