I know you can go to http://webcache.googleusercontent.com/search?q=cache:http://example.com/ to view Google's cache of any URL, but do they provide an API to hit thousands of these and pay for access?
I don't want to just make HTTP GETs to these URLs too fast and get my IP addresses banned or upset Google.
Just wondering if they offer a way to pay and do this through official channels like they do with their search API.
