Trivia APIs
Trivia APIs here serve either questions or facts. Open Trivia Database is free and keyless, with community-maintained multiple-choice questions across many categories, and QuizBase adds multilingual questions deduplicated from open datasets, each tagged with its source license. Random Useless Facts is the lighter option, returning a random or daily fact in English or German.
