Gemini Notebook Enterprise API
Preview (Pre-GA) REST API on the Google Cloud Discovery Engine service (v1alpha) for Gemini Notebook Enterprise: create, retrieve, list recently viewed, share and batch delete notebooks; batch create, get and batch delete notebook sources (including file upload); create and delete Audio Overviews. Requests authenticate with Google Cloud OAuth 2.0 access tokens and require the Cloud NotebookLM User role (roles/discoveryengine.notebookLmUser) and a Gemini Notebook Enterprise license. The contract is part of Google's own Discovery document for discoveryengine v1alpha (resource projects.locations.notebooks).
