  title: deepset Cloud API (deepset AI Platform)
  description: >-
    Hosted REST API for the deepset AI Platform (deepset Cloud), the commercial
    product built on the open-source Haystack framework. The API lets you manage
    workspaces, create and deploy Haystack pipelines, upload and index files, and
    run searches against deployed pipelines. All resource endpoints are prefixed
    with /api/v1 and authenticated with a Bearer API key generated in the platform
    UI. The open-source Haystack framework itself is a Python library, not a hosted
    REST API; this specification models only the documented deepset Cloud REST
    endpoints.
