Air Quality API

Data

10 tokens / llamada

Latest air-quality readings — PM2.5, PM10, ozone, NO2, SO2, CO and more — from the nearest government and research-grade monitoring station to any coordinates, with a computed US EPA AQI (value, category, dominant pollutant), per-pollutant timestamps and staleness flags, a nearby-station directory, station detail and a pollutant catalogue. Open data via OpenAQ under each station's own government licence (public domain, CC BY, ODC-BY, UK OGL and similar; non-commercial stations excluded), edge-cached for 15 minutes.
