QuizAPI

QuizAPI provides programmatic access to thousands of quiz questions across topics such as programming, science, mathematics, and general knowledge. Developers can use the API to power trivia apps, online assessments, learning platforms, and embedded quizzes on their own websites. Questions can be filtered by category, difficulty, and tags, and quizzes can be created and managed through a JSON REST API.

QuizAPI publishes 3 APIs on the APIs.io network: Discovery API, Questions API, and Quizzes API. Tagged areas include Quizzes, Trivia, Education, Assessment, and Content.

QuizAPI’s developer surface includes authentication, documentation, signup flow, support, engineering blog, and 4 more developer resources.
