The Air Quality API supports the following response content types:

You can specify the response content type by setting the Accept header in your request. If you don't specify a content type, the API will default to application/json.


# Here is a curl example
curl \
-X GET \
-H 'x-api-key={{YOUR-API-KEY}}' \
-F 'auth=true' \

The Air Quality API uses an API Key to authenticate requests. You can view and manage your API key by visiting your dashboard.

Your API keys carry many privileges. To keep them from being abused, please do not share the keys on client-side code or Github etc. Keep them very secure.

To use any API, you must have it enabled from within your dashboard. Disabled APIs will fail to respond to your requests.

All requests made to the API must contain the header x-api-key in each of your requests. API requests without authentication will fail.

All API requests must also be made over secure HTTPS. Requests made over plain HTTP will fail.

Error Code Meaning
401 Your request was made with invalid credentials. This error also appears when you don't pass the x-api-key header in your request.
403 Typically, this occurs when you are trying to access an API that you have not enabled.

Rate Limits

    "status": "error",
    "data": null,
    "error": "Rate limit exceeded. Please upgrade your subscription plan."

Each subscription has its own rate limit. Your limit is based on your subscription plan (free or paid). If you exceed your limits, don't worry. You can always upgrade or downgrade at any time.

When you reach your limit, the service will stop responding and typically return an HTTP 429 response status code. The error will also contain a details JSON.

The Air Quality API uses the following error code:

Error Code Meaning
429 You have exceeded your rate limit and further requests will be denied until the next cycle.
