# Query data assets in batches

Batch query of generated data assets by original file ID; unprocessed files will not appear in the results.

```text
POST https://moi.matrixorigin.cn/newmoi/catalog/data-assets/batch-get
```

## Preparation before calling

First [query the file list](list-files.md) to obtain the file ID. Prepare a list of personal access tokens, target workspace IDs, and file IDs that have access to the target workspace.

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.
- `$FILE_ID`: Original file ID.

Empty file IDs in requests are ignored, and duplicate IDs are only processed as the first occurrence.

## Request example

```bash
curl -X POST "https://moi.matrixorigin.cn/newmoi/catalog/data-assets/batch-get" \
  -H "X-API-Key: $AI_STUDIO_API_KEY" \
  -H "X-Workspace-ID: $WORKSPACE_ID" \
  -H "Content-Type: application/json" \
  -d '{
    "raw_file_ids": ["'"$FILE_ID"'"]
  }'
```

## Request body

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `raw_file_ids` | string[] | Yes | A list of original file IDs to query. |

`[]` after a type means an array. For example, `string[]` is an array of strings.

## Successful response

Returns `200` on success, `items` contains only processed file assets.

      }
    ],
