Online search script

I'm looking for an online script that I can enter a bunch of URLs into. The script will go to [login to view URL] pull random dates for the site every year for the last five years. I will have a list of keywords to search for. So any website that has one of the keywords listed on the wayback archive page will be filtered out, and the ones that don't have any of the keywords will be kept. Example, you take [login to view URL]: [login to view URL]*/[login to view URL] One random date would be: [login to view URL]://[login to view URL] And say one of my keywords was "AFRICA". Well africa is on that page so that domain would get filtered out of the list of domains I enter. So I may enter 1000 domains at a time. So I need it to check every domain. And I need it to check 10-50 random [login to view URL] dates. It may need proxies to use, which I can supply, but it will need to be able to use proxies to search hundreds and hundreds of [login to view URL] dates. There is more to it that I will explain in message. But that is the main part of it.
