What should API documentation primarily focus on?

• A. What it does
• B. How it works
• C. Both equally
• D. None of the above

Answer: (A)

API documentation should primarily focus on what the API does because understanding its functionality is crucial for developers who intend to use it. This aspect helps users quickly grasp the purpose and capabilities of the API, enabling them to determine if it fits their requirements. Clearly outlining the specific endpoints, data formats, and the operations that can be performed allows developers to utilize the API effectively without needing to wade through unnecessary technical details or implementation nuances. By prioritizing what the API does, the documentation can provide concise descriptions, examples of requests and responses, and use cases which facilitate easier integration and implementation. While knowing how the API works is also important, it typically serves as a secondary consideration after users have established what they can do with it. Technical details about implementation and operational mechanics can greatly assist developers later on but might not be as immediately relevant to someone assessing the API for their project's needs. Thus, emphasizing what the API does first creates a clear and accessible entry point for developers at all levels.
