OpenWeatherMap
OpenWeather (operating openweathermap.org) is a global weather data platform delivering current weather, multi-horizon forecasts, historical archives, climate statistics, air pollution, solar irradiance, road risk, geocoding, and weather map tiles. Data is sourced from satellites, weather models, radars, and a worldwide network of weather stations, served through REST APIs across a freemium, multi-tier, and pay-per-call commercial model.
OpenWeatherMap publishes 14 APIs on the APIs.io network, including Accumulated Parameters API, Air Pollution API, Current Weather API, and 11 more. Tagged areas include Weather, Forecast, Climate, Air Pollution, and Air Quality.
The OpenWeatherMap catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
OpenWeatherMap’s developer surface includes authentication, getting-started guide, API reference, signup flow, developer console, pricing, engineering blog, and 37 more developer resources.
