Real-time air quality and weather data API

Overview

The IQAir API provides real-time and historical air quality data (including AQI, PM2.5, PM10, NO2 levels) and weather metrics (temperature, humidity, wind speed). Key endpoints include location-based queries (coordinates, city), global air quality rankings, and historical trend data. Responses are in JSON format. Use cases include building air quality monitoring apps, integrating into smart home systems, public health dashboards, environmental research tools, or travel platforms to inform users about air quality conditions.
