Built by Metorial, the integration platform for agentic AI.
Retrieve air quality and weather data at the monitoring station level. Supports two modes: specify a station by name (along with city, state, country), or find the nearest station to GPS coordinates / IP location. Station-level data provides more granular pollutant concentration readings than city-level data.
Retrieve current air quality and weather data for a specific city. Returns AQI values (US and China standards), main pollutant, weather conditions (temperature, humidity, pressure, wind), and GPS coordinates. If available on your plan, also returns pollutant concentrations, forecasts, and historical data.
Retrieve a global ranking of major cities by current air quality index (AQI). Enables comparison of air quality across cities worldwide. Returns each city's name, location, and AQI values for both US and China standards.
Retrieve air quality and weather data for the nearest city to a given location. Supports lookup by GPS coordinates (latitude/longitude) or by IP-based geolocation when no coordinates are provided. Useful when the exact city name is unknown.
Browse the IQAir location directory hierarchically. Lists supported countries, states within a country, cities within a state, or monitoring stations within a city. Use this to discover valid location names before querying air quality data.
