Game Night Trivia Pack
Build a game-night quiz with 3 to 10 multiple-choice questions, shuffled options, separate host answer key with explanations, and hosting notes. Uses a finite 36-question locally authored bank in science, geography and general knowledge. Reproducible seed; questions may repeat between packs. No live feed or model generation.
Preview request
The preview path is rate-limited and does not charge. It executes the live source and returns the paid response shape while withholding decision-ready values. Production requests use the same parameters and return a standard x402 challenge when no payment signature is present.
