  title: jService Trivia API
  description: |
    jService is an open source Ruby on Rails API that serves Jeopardy! questions
    (called "clues"), answers, and categories sourced from the J! Archive fan site.

    The schema in this document is reconstructed from the upstream source repository
    (`sottenad/jService`, MIT licensed). The historical public deployment at
    https://jservice.io is offline as of 2025 (parked / for-sale holding page); the
    project remains self-hostable against PostgreSQL.

    All endpoints return JSON. None require authentication; no rate limits are
    documented in the source.
  version: '1.0.0'
