Explanation
An API (Application Programming Interface) provides a structured, programmatic way to request and receive data directly from a source in real time or near-real time. It is the most efficient method because it delivers clean, structured data (often in JSON or XML) without the overhead of parsing HTML. Web scraping extracts data from web pages but is fragile and less efficient. Surveys collect primary data from respondents. Public databases contain static or periodically updated datasets and require manual or batch retrieval. For fresh, on-demand data from a single known source, an API is the gold standard.
