The currentConditions endpoint
provides current hourly air quality information. You can control which AQIs and
pertinent information are returned (such as pollutants concentration level and
health recommendations).
You can request current hourly air quality using the
currentConditions
endpoint by sending an HTTP POST request to:
https://airquality.googleapis.com/v1/currentConditions:lookup?key=YOUR_API_KEY
Include your request options in the JSON request body. The request body contains the location for which you would like to get the air quality current conditions and various options to control what air quality information to include in the response.
Example of basic request
Basic request body
The following code shows how to construct a basic request body for a
currentConditions
request. In this example, you set only the location.
curl -X POST -d '{
"location": {
"latitude": 37.419734,
"longitude": -122.0827784
}
}' \
-H 'Content-Type: application/json' \
'https://airquality.googleapis.com/v1/currentConditions:lookup?key=YOUR_API_KEY'
Basic request response
The call above generates the following JSON response. For more details about the response data, see Response data.
