How to hit the OSRM (routing) API

OSRM computes routes on OpenStreetMap roads. The public demo server at router.project-osrm.org is for testing only. Coordinates are longitude,latitude, separated by semicolons.

Authentication

None. The demo server has a fair-use policy — run your own OSRM for real traffic.
