How to get the distance (KM) between 2 locations in fusion application from OTM appication

I am having source and destination location on the order and i want to know the distance (KM) when i book order in fusion application .

Both the above locations (source & Destination) do exist in Oracle transportation management (OTM). Is there any way where by calling any REST API from OTM to have the distance for the above locations from OTM.

The above can be achieved in OTM by going to Ask Oracle - Distance / Time from the from end.

Is there any REST API in OTM wherein we can get the distance directly by passing the locations as paramaters.

Let me know has came across such requirements.
