Is there a way to extract the mask with an API call?

Not a bug, rather a question/feature request. Like the title says I have been trying to find a way to get the mask only via API call. Is there a way to do this?

[monstari]

Same, I'd like to use it as negative mask.

Yes, but you may need to write an api.py file and put it in the extension folder.
