Jservice API
Overview
Jservice gives you free access to a massive database of Jeopardy! clues and categories with no API key required. You can fetch random clues, search by category, or grab the final Jeopardy question — perfect for building quiz apps or trivia games. Just send a GET request to get started instantly.
Beginner Tip
Start with the /random endpoint to fetch a single clue — the response includes the question, answer, category, and point value. No authentication needed, so you can test directly in your browser.
