Air Quality API
How clean the air is right now at official monitoring stations near any place in Europe.
Used by: Developers and data teams.
Live air quality for any place in Europe, no API key: newest hourly PM2.5, PM10, NO2, ozone and SO2 measured by official EEA monitoring stations (3,700+ active stations in 38 countries incl. UK), the nearest stations to a lat/lon with distance, European Air Quality Index band, data age, hourly history up to 30 days and station lists. Only-new mode returns each new hour once.

Inputs
| Field | Type | Description |
|---|---|---|
mode | string | latest = newest hourly values at the stations nearest to a place (with European Air Quality Index band); history = hourly values of one station for the last N hours; stations = list all stations of a country. |
lat | number | Latitude of the place, e.g. 52.52 (Berlin). Europe only (EEA member and cooperating countries, plus UK). |
lon | number | Longitude of the place, e.g. 13.405 (Berlin). |
locations | array | For latest: up to 25 places as 'lat,lon', e.g. 48.8566,2.3522. Each place returns its nearest stations; rows carry query_location. |
station | string | EEA station EoI code, e.g. DEBE068 or FR04055. Required for history unless lat/lon is given (then the nearest station is used). |
country | string | For stations: ISO 2-letter country code, e.g. DE, FR, BG, PL. |
pollutants | array | Any of PM2.5, PM10, NO2, O3, SO2. Empty = all five. |
radius_km | integer | For latest: search radius around the place. Default 25, max 200. If no station is inside, the nearest ones are returned with a note. |
limit | integer | For latest: how many nearest stations to return per place (default 3, max 20). For stations mode: max rows (default 500). |
hours | integer | For history: how many past hours to return (default 24, max 720 = 30 days). |
onlyNew | boolean | Monitor mode: return only station hours not returned before for this Monitor ID. Schedule the actor hourly to get each new measurement once. |
monitorId | string | Name of the only-new memory, so several schedules stay separate, e.g. 'berlin-office'. |
