The Weather Company API from IBM Watson & Cloud Platform operates the weather data from weather.com, intellicast.com, and Weather Underground. What used to be separate company APIs are now encompassed into The Weather Company Data Core API. Aimed at business customers, data offered through this API includes current conditions, 2-day hourly forecast, site based observations, time series observations, weather alerts, daily and monthly almanac, radar and satellite images, location services, and more. Developer wishing to access the API or documentation need to contact the provider. The Weather Company offers other weather API packages as well.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
