API(s) to find out destination location associated with a particular item and LPN

Summary:

We are trying to build a custom VBCS application for dropping LPN content into active location once it is picked, because of limitation of current WMS drop logic to sequence task in proper order. Our challenge right now is to find out destination location using LPN and item, we have find out a way but it takes around 6 rest api call. Is there a better way to achieve this functionality?
