How this service works
Current air quality at a place: PM2.5 and PM10 (µg/m³), US and European AQI, from Copernicus CAMS via Open-Meteo, with a signed receipt. Send latitude and longitude, or a city.
Output
Returns current particulate matter concentrations (PM2.5 and PM10 in µg/m³), the US AQI index value, and the European AQI index value for the requested location, along with a cryptographically signed receipt confirming the data provenance.
Example use cases
Pre-run outdoor air check
“Before I head out for my morning run in Denver, can you check the current air quality — I want to know the PM2.5 level and the US AQI so I know if it's safe to exercise outside?”
Travel health advisory lookup
“I'm about to land in Beijing — what's the current air quality there? Give me the PM2.5, PM10, and European AQI so I can decide whether to wear a mask.”
Verified air quality report for records
“Can you get me a signed, verifiable air quality reading for latitude 48.8566, longitude 2.3522 — I need the PM2.5, PM10, and AQI values with a receipt I can keep as proof.”
Technical details
Endpoint
POSThttps://modelmarket.dev/x402/air-quality-now?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, point-in-time air quality data (PM2.5, PM10, US AQI, European AQI) for a specific location and want a cryptographically signed receipt as provenance proof. It is ideal for health-safety checks, regulatory compliance records, or any workflow where verifiable environmental data is required. Prefer it over generic weather APIs when particulate matter and AQI — not just temperature or wind — are the primary concern.
Side effects
- Invalid or out-of-range latitude/longitude values return a validation error
- Unrecognized city names may return a geocoding failure or no-data response
- Copernicus CAMS data temporarily unavailable for a region results in a service error
- Payment not processed (x402 protocol failure) returns a 402 Payment Required response
- Request missing both city and coordinates returns an input validation error
