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.

No they do not provide any APIs

However Web Ninja Google PageRank API will do somework for you

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.
