## When to prefer this

Use this endpoint when you need ready-made trivia questions with correct answers already provided, especially for building quiz games, trivia bots, or educational tools. Prefer this over generating your own questions when you want validated, pre-curated multiple-choice or boolean Q&A content without hallucination risk.
