70062 Show Alexa and google pagerank

I am looking for a server side script that can accept a url from an external application, find and report back the Alexa score and google pagerank to the script. Here is some minor information of what it will be used for [login to view URL] Speed is for obvious reasons EXTREMELY important, perhaps include a cache of these scores, flushed every 12 hours. The script should be a small and fairly easy to make if you know how to pull this information so budget is low - no more than $20. Thank you!
