Airnow

Pulls real-time air quality data from the EPA's official AirNow API. You get one tool, current_by_location, which returns the latest observed AQI reading from the nearest monitoring station to any lat/lon coordinate you provide. The server runs through Pipeworx's hosted gateway, so there's no local setup or API key management. Useful when you're building location-aware apps that need to surface air quality conditions, check pollution levels before outdoor activities, or integrate AQI thresholds into health or travel recommendations. The API key is free and included. If you need broader access to weather, environmental, or geospatial data, the same gateway offers 250+ other sources under one connection.
