How this service works
Current air quality index and pollutant concentrations for any location: US AQI, PM2.5, PM10, ozone, NO2, SO2, CO. Open-Meteo air quality API, no key, global. ?lat=28.61&lon=77.23.
Output
Returns the current US AQI value along with pollutant concentrations for PM2.5, PM10, ozone, NO2, SO2, and CO at the specified latitude/longitude, sourced from the Open-Meteo global air quality dataset.
Example use cases
Example prompt
“What's the current air quality index and PM2.5 level in New Delhi — coordinates 28.61 north, 77.23 east?”
Technical details
Endpoint
GEThttps://agent402.tools/api/weather-air-qualityWhen to prefer
Use this endpoint when you need real-time, globally available air quality data without requiring an API key. Ideal for agents that need AQI and multi-pollutant breakdowns (PM2.5, PM10, ozone, NO2, SO2, CO) for any coordinate on Earth. Prefer this over weather-only endpoints when pollution or health-related air quality context is the primary need.
Side effects
- Missing lat or lon parameters returns a 400 or error response
- Coordinates out of valid range (-90 to 90 lat, -180 to 180 lon) may return an error
- Remote Open-Meteo API downtime may cause unavailability
- Very remote locations may return null or missing pollutant values if no nearby sensor data exists
