#knowledge

A ready-to-use trivia engine with more than 44,000 multiple-choice questions across 20 categories — animals, brain teasers, celebrities, entertainment, kids, general knowledge, geography, history, hobbies, humanities, literature, movies, music, people, religion, science & technology, sports, television, video games and world. Pull a random question or a batch (optionally filtered by category, with the answer hidden for gameplay and the options shuffled), fetch a specific question by id, verify a submitted answer, search questions by keyword, and list every category with its question count. Every endpoint accepts input via the query string or the request body and returns lean JSON. Pure server-side data (no third-party upstream), so responses are instant and always available. Ideal for quiz and trivia games, pub-quiz and party apps, learning tools, chatbots and Discord/Slack bots.
