– in the U.S. Supreme Court opinion, Google v. Oracle 2021, pp. 3–7 – "For each task, there is computer code; API (also known as Application Program Interface) is the method for calling that ' computer code ' (instruction – like a recipe – rather than cooking instruction, this is machine instruction) to be carry out"

Traditionally, API referred to an interface connected to an application created with any of the low-level programming languages, such as JavaScript. However, modern APIs vary in their architectures and use of data formats.

While links aren't commonly used in APIs, some prominent web APIs like Google Drive API and GitHub API represent relationships using links based on HTTP URLs. Why is this the case?

APIs make it easier to access to a variety of resources. They also allow cross-platform communication which solves certain business logic. APIs hosted and created by a third-party application can significantly reduce the amount of work within your organization. This, in turn, will speed up the development process of an application.
