FlexWeather is an API that provides weather data for the US and Germany. It is functionally a wrapper for the the National Weather Service API and Deutscher Wetterdienst (via the wonderful work of BrightSky).
This project was created largely as a functional experiment by Darren Krape. If you have questions about this API, please get in touch!
Note that the API is rate limited and does cache results for about a minute.
