AI-generated

Summary

List items from a specified Langfuse annotation queue, optionally supporting pagination and limit controls.

Inputs

  • Queue ID (required) — The ID of the annotation queue from which to fetch or list items.
  • Show Advanced Fields — Toggle to reveal additional optional parameters for the operation.
  • Query JSON — A JSON string representing query parameters such as page number and limit for pagination; must be enabled via 'Show Advanced Fields'.
  • Return All — Boolean flag to return all results by auto-paginating through all pages, ignoring limits.

Output shape

a list of annotation queue items returned from Langfuse's Public API endpoint.

If 'Return All' is true, the operation retrieves all pages of items automatically. The 'Query JSON' parameter allows fine control over pagination parameters. The operation requires a valid Queue ID. Errors encounter partial success status codes (e.g. 207) which include error details without failing the entire request.
