How this service works
Air quality index (AQI) with PM2.5, PM10, NO2, O3, CO, SO2 for any location
Output
Returns an AQI object with a numeric index (1-5) and label (e.g. 'Moderate'), plus individual concentrations in μg/m³ for CO, NO, NO2, O3, SO2, PM2.5, PM10, and NH3, along with the measurement timestamp and coordinates.
Example use cases
Example prompt
“What's the current air quality index and pollutant breakdown — PM2.5, PM10, ozone, NO2 — for San Francisco right now? Use latitude 37.7749 and longitude -122.4194.”
Technical details
Endpoint
GEThttps://openweather-coral.vercel.app/weather/air-qualityWhen to prefer
Use this endpoint when you need real-time air pollution data including granular pollutant concentrations (PM2.5, PM10, NO2, O3, CO, SO2) for a specific latitude/longitude or city. It is ideal for health-aware applications, travel planning, or environmental monitoring workflows that need AQI alongside specific chemical component levels.
Side effects
- Invalid or out-of-range latitude/longitude returns an error
- Missing required query parameters (no lat/lon or city) returns a 400-type error
- Unrecognized city name may fail to resolve coordinates
- Payment failure (insufficient balance) returns 402
- Service unavailability from upstream OpenWeatherMap returns a 5xx error
