Pagerank Lookup and Google API

With the general thought that google offers many possibilities with their seemingly endless API’s I began on a project today that seemed quite simple in nature.  I would use the google api to see if a page was in the cache, and if not then flag it and link to it from somewhere.

The first roadblock I found was that the SOAP Google API no longer offers support, and I could not find their examples anywhere online.

Then I thought, why not just get the pagerank and see if when it is not cached it returns N/A then I could just assume it is not cached.  I searched long and hard for working codes, but the checksums must have been wrong or something because they have all been giving me the forbidden  403 error.  The main script I used was the Google Pagerank Checker, and it was quite unfortunate when it did not work, because it looked like it offered so much promise.
