Remove a label from its notebook. Its sources are not deleted: they stay in the notebook, without this label. To remove a source itself use DELETE /sources/source.

https://api.useapi.net/v1/gemini-notebook/labels/label

  • label is required, the label id from GET /labels or POST /labels, URL-encoded in the path (it contains : and @). The id names its account and notebook, so no email or notebook is needed.

Authorization: Bearer {API token}

  • 401 Unauthorized

    Invalid API token.

    {
  "error": "useapi.net ⁝ Unauthorized",
  "code": 401
}

  • 403 Forbidden

    The id was issued to a different API token.

    {
  "error": "user:[email protected]:d02c903b-17f8-4241-a263-2be9e7359d55:5973ba2b-845e-41b5-97b2-ef855d5746ad does not belong to this API token",
  "code": 403
}

  • 404 Not Found

    The label is no longer in the notebook, the notebook was deleted, or its account is no longer configured.

    {
  "error": "Label user:[email protected]:d02c903b-17f8-4241-a263-2be9e7359d55:5973ba2b-845e-41b5-97b2-ef855d5746ad not found",
  "code": 404
}

  • 596 Account Error

    Google reported the account as signed out. While we re-check it, the answer is the first message below. Retry in about a minute. If it stays signed out, the account is paused, you receive an email, and the answer becomes the second message until you re-add it via Setup Gemini Notebook.

    {
  "error": "Google reported this account as signed out. We are re-checking it — please retry in about a minute. If it stays signed out, you will receive a re-add email.",
  "code": 596
}

    {
  "error": "Account [email protected]: Google signed this account out. Re-add it at https://useapi.net/docs/start-here/setup-gemini-notebook",
  "code": 596
}

  • 503 Service Unavailable

    Google is temporarily unavailable or is challenging our network. Retry in a few minutes. A 502 means Google answered with an unexpected error.

    {
  "error": "Google is temporarily unavailable (GyzE7e grpc 14), please retry",
  "code": 503
}
