How this service works
Current U.S. EPA Air Quality Index (AQI) and pollution levels for a specific location, given latitude/longitude — use to check smog, air pollution, or whether it's safe to be outside. Sourced from the EPA AirNow program (federal/state/local/tribal agencies); covers the US, Canada, and Mexico only. Data is preliminary and unvalidated per EPA data use guidelines — not for regulatory use.
Output
Returns a JSON object with the current AQI readings array (pollutant-level data), reporting area name, state code, date, hour of measurement, data source, attribution string, and a preliminary boolean flag indicating the data is unvalidated per EPA guidelines.
Example use cases
Example prompt
“What's the current EPA AirNow air quality index near latitude 34.0522, longitude -118.2437? I want to know if it's safe to go for a run outside.”

Endpoint
GEThttps://x402-seller.onrender.com/air/qualityWhen to prefer
Use this endpoint when you need real-time, federally-sourced AQI data for a specific geographic point within the US, Canada, or Mexico. It is backed by the official EPA AirNow network (federal, state, local, and tribal agencies), making it authoritative for public health awareness use cases — though not suitable for regulatory or enforcement decisions due to preliminary/unvalidated data status.
Side effects
- Coordinates outside US/Canada/Mexico coverage area return no data or an error
- No monitoring stations near given coordinates may return empty readings array
- Stale or missing data when EPA AirNow feed is delayed
- Invalid lat/lng format (e.g. non-numeric strings) causes a 400-level error
- Service downtime on Render hosting platform returns 5xx error
