Road Risk API

Road Risk API concept

Road Risk API provides weather data and national alerts at the point of destination and along a route.

Road Risk API responds weather data with national alerts along a route that is set up as a massive of points where each point is a pair of latitude, longitude and time. For each point, the API returns air temperature, wind, precipitation, dew point. For the US and EU territories, we also provide road surface temperature and black ice road state. Active national alerts include alert description, national agency name, and the event hazardous level.

Weather forecast is available for 5 days with minute granularity for the 2 hours from the current moment and hourly granularity for the rest. Historical data is accessible for 1 previous year.
