  title: Orama Cloud API
  description: >-
    Specification of the Orama Cloud REST API. Orama Cloud is the hosted,
    managed platform built on the open-source Orama search engine. It exposes
    three host families: a webhook management API for index administration and
    document ingestion (api.askorama.ai), a per-index search host
    (cloud.orama.run), and an answer/RAG host (answer.api.orama.com). The
    open-source @orama/orama library itself is a JavaScript library invoked via
    function calls and is not modeled here as an HTTP API.
