# Delete dataset items

POST http://localhost:5173/api/v1/private/datasets/items/delete
Content-Type: application/json

Delete dataset items using one of two modes:
1. **Delete by IDs**: Provide 'item_ids' to delete specific items by their IDs
2. **Delete by filters**: Provide 'dataset_id' with optional 'filters' to delete items matching criteria

When using filters, an empty 'filters' array will delete all items in the specified dataset.
