    "mode": 2
  }'
```

## Error Code Description

| Error Code | Error Message | Description | Solution |
|------------|---------------|-------------|----------|
| 1001 | Parameter validation failed | `mode` is outside 0-2 or has the wrong type | Pass 0, 1 or 2 |
| 2040 | Get filter list failed | Failed while reading the filter metadata | Retry or contact technical support |

## Notes

1. **No Draft Needed**: this interface is read-only and does not touch any draft
2. **Name Matching**: `name` is exactly the value accepted by `add_filters` as `filter_title`
3. **List Size**: the list comes from the local JianYing metadata and changes with the built-in metadata version (currently 1052 filters: 802 VIP, 250 free)
4. **Use with add_filters**: names returned here are guaranteed to resolve; unmatched names make `add_filters` fail with 2039

## Workflow

1. Validate the `mode` parameter
2. Read the filter metadata
3. Keep all / VIP / free filters according to `mode`
4. Return the filter object array
