Question
Which of the following is the primary benefit of using
APIs over web scraping for data collection from a website?Solution
APIs (Application Programming Interfaces) are specifically designed for data sharing and allow structured, reliable, and lawful access to a website’s data, often in real-time. Unlike web scraping, APIs offer data in a standardized format (such as JSON or XML), which simplifies data extraction and makes processing easier. APIs also come with clear terms of use and generally ensure compliance with a website’s data access policies. This benefit of structured, real-time data collection without legal risk makes APIs the preferred choice when available, particularly for data analysts who require accuracy, compliance, and easy parsing for analysis. The other options are incorrect because: • Option 1 is incorrect; web scraping can access most public pages but may violate terms of service, whereas APIs limit access to authorized data and are structured for safer extraction. • Option 3 is inaccurate; the speed of data retrieval depends on various factors, including server load and API rate limits, so APIs are not universally faster. • Option 4 is incorrect; APIs often require authentication (like API keys), while web scraping might not need login credentials for public data. • Option 5 is incorrect because APIs restrict access to private data without proper authorization, while web scraping cannot legally bypass these restrictions.
