Road Weather Analytics
https://data.api.xweather.com/roadweather/analytics/The roadweather/analytics endpoint is powered by the advanced and precise Vaisala Xweather road weather forecasts and provides complete access to the Vaisala Xweather road weather forecasts. With the Road Weather Analytics endpoint the API further details the road surface condition (dry, wet, snow, ice) and road surface temperature, comprehensive road weather insights, including water, snow, and ice thickness, hydroplane and turnover probabilities, visibility, and fog probabilities. Enhance your application's capabilities with this cutting-edge road weather endpoint to help users make better-informed decisions and promote safer driving experiences.
Road weather forecasts are available at 15-minute intervals for the first 2 hours, then hourly intervals for up to 24 hours.
Requests
Every request to the endpoint must include one of the supported actions in the url.
