An API, or Application Programming Interface, is a set of rules and protocols that defines how software components should interact. It provides a way for different software systems to communicate with each other, allowing them to exchange data and functionality.
Examples of APIs include the Twitter API, which allows developers to access Twitter data and build applications that integrate with the social media platform; the Google Maps API, which enables developers to use Google’s mapping technology in their own applications; and the Stripe API, which provides a way for developers to integrate payment processing capabilities into their applications.
