Air Quality API v2
The Air Quality API lets you request air quality information including indexes, pollutants, and health recommendations for a specific location. The API provides endpoints that let you query:
- Current Conditions
- Hourly Forecast for up to four days
- Hourly History for a maximum of 30 days
Current Conditions
Returns current air-quality conditions for a specific location

Default Request Settings
This example shows a request to get the current air quality conditions for central Paris (48.857456, 2.354611) using the default request parameters settings.
https://api.breezometer.com/air-quality/v2/current-conditions?lat=48.857456&lon=2.354611&key=YOUR_API_KEY TIP

Customizing API Requests
You can customize any API request to only include the data you need for your software. This allows you to save bandwidth and decrease response time by requesting less information. You customize request data returned using the features parameter to define the feature or list of features to include in the response.
Example
The following returns current air quality conditions including the breezometer_aqi, local_aqi, and sources_and_effects features:
https://api.breezometer.com/air-quality/v2/current-conditions?lat=48.857456&lon=2.354611&key=YOUR_API_KEY&features=breezometer_aqi,local_aqi,sources_and_effects TIP
Note:
Unless you have specified the features parameter in the request, the response returns only the BreezoMeter AQI information.

Metadata
Request Metadata
Any request to an API endpoint can return metadata that describes the original request. You request metadata by including the metadata parameter in your request with the value true. When excluding the metadata parameter, or setting it to false, the metadata field returns null.
When requested, it has slightly different structure, depending on the request type.
Single Object
Requests for a specific date and time return a single object, and a metadata object with a single timestamp. This example shows a request to the hourly forecast endpoint for a specific date and time that returns metadata:
https://api.breezometer.com/air-quality/v2/forecast/hourly?lat=48.857456&lon=2.354611&key=YOUR_API_KEY&datetime=&metadata=true
The request returns this metadata object as part of the response:
"loading..."Array of Objects
Requests for the next number of hours or time period return an array of objects, and a metadata object with a range of timestamps. This example shows a request to the hourly forecast API endpoint for the next three hours that returns metadata:
https://api.breezometer.com/air-quality/v2/forecast/hourly?lat=48.857456&lon=2.354611&key=YOUR_API_KEY&hours=3&metadata=true The request’s JSON response includes the following metadata object:
