  title: Docling Serve REST Tasks API
  description: 'HTTP service exposing the Docling document-parsing pipeline. Submit documents as URLs

    or uploads and receive a `DoclingDocument` together with optional Markdown, HTML, and

    text renditions. Synchronous endpoints return the converted document inline; the

    asynchronous endpoints return a task handle that can be polled, streamed over

    WebSocket, and fetched on completion.
