Query pagerank from Google API?

I have a script that calls the Google API server to return the top 8 results for any given query. However, the one piece of data that's missing is the pagerank.

I'd like to find out if its possible to add a querystring paramater to get the PR.

Here is my current query...开发者_如何学编程

https://ajax.googleapis.com/ajax/services/search/web?v=1.0&rsz=8&q=search+engine+optimization

And based one a bit of research, I've found that some are using the "features=Rank" parameter, however, I see no difference in the results.

Google does not generally expose PageRank publicly. The closest they've gotten in the past is displaying a number which resembles PageRank in the Google Toolbar, and it's pretty well known that the values shown in there are per-site, not per-page, and are not updated frequently.
