OpenWeatherMap is nonFree but the data is free --> https://openweathermap.org/faq
The thing is weird because of the way it is published in their FAQ because of the section telling “our product and services”, but they refer to be as-is in the way it is exposed (maybe understood as client-side). There is not server-side free hosted in any repository or provided by them.
This is the reason why only the data is the really free thing.
