API

These docs are for developers and businesses building on the QuestionStock API. The Business plan unlocks authenticated content API access for personal workspaces, while most creators stay in Free or Pro and work directly in My Quizzes.

QuestionStock includes first-party quiz play in its own product, but the Business API is a content API rather than a gameplay backend. It delivers question content and supporting metadata while your app remains responsible for players, attempts, submissions, timers, scores, leaderboards, multiplayer rooms, and session logic.
