API to get filament used or extruder moved distance during print

WindoAC

(I post here since no response in Feature Requests)

I would like to implement filament jam detection function by an external python script. I am looking for getting the filament used or extruder moved distance during print. But search all API document did not found any way to get the filament usage real-time.

Request to add filamentUsage or extruderUsage output in API listPrinter or stateList.

Adding it there will add much communication all the time. So that is not really what I'd like to do.
Maybe a separate command so it only gets queried if really wanted.

Great! Looking forward to having this counter value from API.

Thanks!
