Query root volume details by ID.

```text
POST https://moi.matrixorigin.cn/newmoi/catalog/volume/info
```

## Preparation before calling

First [query the object](list-database-objects.md) in the database to obtain the target volume ID. Prepare the personal access token, target workspace ID, and volume ID 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.
- `$VOLUME_ID`: Volume ID to query.

## Request example

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