  title: Keen Cached Queries API
  description: >-
    The Keen Cached Queries API allows developers to create, manage, and
    retrieve pre-defined queries that are automatically refreshed on a
    schedule. Cached queries improve performance for frequently accessed
    analytics by storing pre-computed results, making them ideal for
    powering dashboards and embedded analytics experiences without
    incurring per-request rate limits.
