GET /api/air-quality
unprobed
Real-time and forecast air quality index (AQI) and particulate matter database. Retrieves PM2.5, PM10, ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), US AQI scale labels, and European AQI parameters for any location globally. Crucial for smart city analytics, health monitoring, outdoor event planning, and environmental geointelligence.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
