I'd be especially interested in a crawl results API if it could distinguish "news" sites from other content. Some of our work involves analyzing content, extracting keywords and then looking for relevant news (and other context) around those keywords. Of course the crawl would need to be relatively fresh to be useful for that.

Worst case we may build our own specialized crawler just for this purpose, but it would be nice if there was a useful search engine API we could leverage. And, of course, we'd be happy to pay for access to such an API.
