What are the four primary components of an API?

APIs define how different software components communicate. The primary components are methods (the types of operations, e.g., HTTP verbs), actions (specific behaviors or tasks invoked by a method), objects (the resources or data entities that the API interacts with), and formats (the structure in which data is exchanged, such as JSON or XML).

These are components of a network device's configuration and operational state, not the generic components of an Application Programming Interface.

GET, PUT, and DELETE are specific HTTP methods commonly used in RESTful APIs, but SET is not a standard HTTP method; these are examples of methods, not the complete primary components of an API itself.

Modularity, Abstraction, Stability, and Resources are often characteristics or principles of good API design, but not the fundamental structural components of an API definition.
