1. Locations API

AccuWeather’s Locations API gives you a place ID for later calls. In OpenWeather you don’t need that ID — all weather endpoints accept latitude and longitude. Our Geocoding API turns city names into coordinates and vice versa, so you can show a city name in your app and call weather data by coordinates.

  • OpenWeather URLs:
    • Current Weather API: https://api.openweathermap.org/data/2.5/weather?lat={lat}&lon={lon}&appid={API key}

  • OpenWeather URLs:
    • UV Index (via One Call API): https://api.openweathermap.org/data/3.0/onecall?lat={lat}&lon={lon}&appid={API key}
