# Cancel async query (nodes)

Cancels an in-progress async node query. Once canceled, polling [GetQuerySpecNodesAsync](/4yItIzMvkpAvMVFAamTf/developers/api/query-builder/getqueryspecnodesasync.md) for the same `query_result_id` returns `UNKNOWN` status and results are no longer retrievable.

### Request body

| Field             | Description                                                                                                                           |
| ----------------- | ------------------------------------------------------------------------------------------------------------------------------------- |
| `query_result_id` | The task ID returned by [CreateQuerySpecNodesAsync](/4yItIzMvkpAvMVFAamTf/developers/api/query-builder/createqueryspecnodesasync.md). |

```bash
curl -X POST "$BASE_URL/api/v1/assessments/query_spec:nodes_async_cancel" \
  -H "Authorization: Bearer $VEZA_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"query_result_id": "<query-result-id>"}'
```

A `200 OK` with an empty body indicates the cancellation was accepted. After cancellation, polling [GetQuerySpecNodesAsync](/4yItIzMvkpAvMVFAamTf/developers/api/query-builder/getqueryspecnodesasync.md) for the same `query_result_id` returns `UNKNOWN` status and results are no longer retrievable.
