google doesn't give out soap keys anymore, so the only way to get this data from them is to break TOS and scrape it. msn took link: data out of it's api and search a long time ago. yahoo is the only one you can get this full data on anymore.

google will also block you as 'virus infected' or similar if you make too many automated requests. i don't recall what the actual number was, but if you try to scrape data on too many sites from 1 host, you'll be blocked for 24hrs.
