Public API for Annotation Queues

Marc Klingen

Access and manage your annotation queues programmatically with our new Public API endpoints.

Annotation queues help to label and review LLM Traces in Langfuse and are often a baseline for any LLM evaluation. This change adds a new public API to manage annotation queues programmatically. Thereby, you can now scale and automate your annotation workflows.

Check out our API docs for detailed information on how to use these new endpoints.

Endpoints:

• GET /api/public/annotation-queues - Get all annotation queues
• GET /api/public/annotation-queues/{queueId} - Get an annotation queue by ID
• GET /api/public/annotation-queues/{queueId}/items - Get items for a specific annotation queue
• POST /api/public/annotation-queues/{queueId}/items - Add an item to an annotation queue
• GET /api/public/annotation-queues/{queueId}/items/{itemId} - Get a specific item from an annotation queue
• PATCH /api/public/annotation-queues/{queueId}/items/{itemId} - Update an annotation queue item
• DELETE /api/public/annotation-queues/{queueId}/items/{itemId} - Remove an item from an annotation queue
