But when you live in Beijing you would be interested in getting this information updated more regularly throughout the day. Especially, if you want to go for outdoor activities, you better check the air quality as the air is really bad in winter. Today early afternoon, the API was over 400! Now, 11pm it is down to 107.
You can find the information via www.bjair.info
actual information and overview throughout the day
The Beijing Air Quality Index of www.bjair.info shows the actual API. It also shows the actual level or grade of pollution based on US standards, all levels of the last 24 hours (by colour) and its lowest and highest API of the last 24 hours.
the scale is divided in 6 levels based on the US standards
This information above is provided by the US Embassy. But the data is collected by anonymous in Chaoyang District and twittered every one or two hours (see below):

Today at 11pm, the API was down to 107 (via www.BJair.info) while the Ministry of Environmental Protection indicates a similar API of 109 - but that shows only the lowest particle rate for the day.
