Overview
APIXU (now rebranded as Weatherstack) is a weather data API that provides current conditions, forecasts, and historical weather for locations around the world. You call the API with your key and a city name or coordinates to receive structured JSON weather data. It is beginner-friendly thanks to its simple query format and clear documentation.
Beginner Tip
APIXU has been rebranded to Weatherstack, so new sign-ups and active keys are managed at weatherstack.com. Use the same endpoint structure with your Weatherstack access_key to continue accessing weather data.
