Is there any API that gives me the page rank of a website programmatically?
回答1:
if you mean with pagerank the green bar on top of the google toolbar, just make a get request to
http://toolbarqueries.google.at/tbr?features=Rank&sourceid=navclient-ff&client=navclient-auto-ff&googleip=O;173.194.35.104;539&iqrn=O6uB&querytime=5X&orig=0gjuj&swwk=-1&ch=805513e7f&q=info:https://stackoverflow.com/
the last figure is the google toolbar pagerank figure (also known as green bar pagerank)
but it is not the real google pagerank (which isn't a figure beteween 0 and 10) and it is not even an estimate of the value of your page, it is just a figure google communicates to webmasters to turn on the "submit data to us" option of the toolbar. my recommendation is: just ignore it.

Sorry to dig up an old question, but I had this same problem, and found a way to solve it.
The "&ch=" part is a checksum of the domain/page you are trying to find the "fake PR" for.
Use the code from here: http://www.codeproject.com/Articles/20038/Request-Google-s-Page-rank-Programmatically
