The Apixu API provides weather data for developing weather apps. The RESTful API uses JSON over HTTP for requests/returns and requires an API Key for authentication. Apixu offers data for real-time weather, 10 day weather forecast, astronomy, time zone, and location. A few of the available methods include: maximum and minimum temperature, wind speed, sun and moon rise/set, and "feels like" temperatures. See the API documentation for full method descriptions and information on how to get started developing with Apixu.
