I'm looking for a directions API with the capacity to perform circular routes - i.e where the origin and destination are the same and route is optimised by factors such as distance and elevation.
Requirements - Simple to implement - IOS + Android compatible - Well documented and supported
I have looked in to Google directions API, TomTom Routing API and HERE API, and have not found ways to implement what I need (though please correct me if these APIs are capable of what I need).
Any help would be much appreciated.
Thanks :) Alex
