The Air Quality API lets you request air quality data for a specific location,
including over 70 air quality indexes (AQIs), pollutants, and health
recommendations. It covers over 100 countries with a resolution of 500 x 500
meters.
Why use the Air Quality API
The API provides endpoints that let you query:
Current Conditions: Real-time hourly air quality information.
Hourly History: Air quality history for a specific location, for a given
time range, up to a maximum of 30 days.
Heatmaps: Color coded tiles of various indexes and pollutants.
Hourly Forecast: Future air quality conditions for a specific location,
up to 96 hours (4 days).
Features of the Air Quality API
Real-time air quality indexes and categories: The Air Quality API
continuously calculates the value of various air quality indexes with 500 x
500 meters resolution.
Health recommendations: Hundreds of research-backed health
recommendations for the general public and sensitivity groups including:
children, elderly, pregnant women, athletes and those with asthma or heart
conditions.
Pollutant details: In-depth information about different pollutants,
highlighting the dominant pollutant, concentrations, sources and effects.
Hourly history: Air quality history for a specific location for a given
time range. Each response potentially includes hourly air quality indexes,
pollutant data, and health recommendations for a maximum of 720 hours (30
days).
Heatmaps: Heatmaps are a collection of AQ indexes and pollutants image
tiles that can be displayed on top of a Google Map.
If your billing address is in the European Economic Area (EEA), you may
display heatmaps on top of any map.

Hourly forecast: Future air quality conditions for a specific location,
and for a given time range or for a particular hour in the future, up to 96
hours (4 days). Each response potentially includes hourly air quality
forecast indexes, pollutant data and actionable recommendations.
How the Air Quality API works
The Air Quality API has the following methods:
currentConditions: The
currentConditions endpoint
provides current hourly air quality information.
history: The
history endpoint provides
historical hourly air quality information for a specific location, for a
given time range, up to a maximum of 30 days.
heatmapTiles: The heatmapTiles
endpoint provides air quality related heatmaps through a tile overlay.
forecast: The forecast
endpoint provides hourly future air quality information for a specific
location, for a given time range, up to a maximum of 96 hours (4 days).
Air Quality API country and region coverage
See Air Quality API supported countries and available AQIs for the
latest coverage details, on a country-by-country basis, for which air quality
information (AQI) and local air quality information (LAQI) is available.
