Request

A request for speed limits must be sent via HTTPS, and takes the following form:

https://mapsdk.navmii.com/api/speedLimits?path=PATH&units=UNITS&key=API_KEY

Parameters
PATHA list of latitude/longitude pairs representing a path. Latitude and longitude values must be separated by commas. Latitude/longitude pairs must be separated by the pipe character: "|". When you supply the path parameter, the API first snaps the path to the most likely road traveled by a vehicle, then determines the speed limit for the relevant road segment.
UNITS

KPH - kilometers per hour

MPH - miles per hour

API_KEYYour API key provided by Navmii
