# Query task details

Read an export task and its file statistics.

```text
POST https://moi.matrixorigin.cn/newmoi/export/task/info
```

## Preparation before calling

First [Query task list](list-export-tasks.md) to confirm the export tasks you want to view. Prepare a personal access token with access to the target workspace, the target workspace ID, and the export task ID.

The example below uses:

- `$AI_STUDIO_API_KEY`: The actual personal access token, passed through the `X-API-Key` Header.
- `$WORKSPACE_ID`: Target workspace ID, passed through `X-Workspace-ID` Header.
- `$TASK_ID`: The export task ID to be viewed, fill in the `id` field of the request body.

## Request example

```bash
curl -X POST "https://moi.matrixorigin.cn/newmoi/export/task/info" \
  -H "X-API-Key: $AI_STUDIO_API_KEY" \
  -H "X-Workspace-ID: $WORKSPACE_ID" \
  -H 'Content-Type: application/json' \
  -d '{
    "id": "'$TASK_ID'"
  }'
```

## Request body

| Field | Type | Is it required | Description |
| --- | --- | --- | --- |
| `id` | string | Yes | The export task ID to be queried. |

`[]` after a type denotes an array. `[]` in a field path denotes each item in an array.

## Successful response

Returns `200` on success. `data` contains task definition and file statistics; task `status` is `2` only means that the task has been completed, and `file_stats.failed` should still be used to determine whether there is a failed file.

```json

  "msg": "OK",
  "data": {
    "id": "export-task-123",
