  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.
