How this service works
Real-time air quality (PM2.5, PM10, ozone, NO2, European AQI) for any lat/lon via Open-Meteo. Free, no key. $0.01 USDC via x402 on Base.
Output
A JSON object with an 'ok' boolean and a 'result' object containing real-time air quality readings for the requested coordinate, including PM2.5, PM10, ozone (O3), nitrogen dioxide (NO2), and the European AQI score, sourced from Open-Meteo's air quality API.
Example use cases
Outdoor run safety check
“Before I go for my run in Central Park, can you check the current air quality at latitude 40.7851, longitude -73.9683? I want to know if PM2.5 and ozone levels are safe.”
Travel destination air quality
“I'm thinking about spending the day outdoors in Paris — can you pull the real-time air quality for latitude 48.8566, longitude 2.3522 and tell me the European AQI and NO2 levels?”
Asthma alert monitoring
“Can you check the current PM2.5 and PM10 concentrations at latitude 34.0522, longitude -118.2437 in Los Angeles? I need to know if it's a bad air day for someone with asthma.”
