For those who don't know, Rollyo is a sort of "search engine" (it really is not, it use Yahoo to power their search) that among other things allow you to create flavors of searches, by listing your favorite websites, or sites that you trust, up to 25 and then perform searches again it. At the bottom, it says "powered by yahoo". I guess they're not using the Yahoo Search API that everybody knows, the one which has limited queries by IP and time. I guess they're using a more powerfull API, or a special, dedicated API. My question, does anybody has any idea about how much would cost a feed like that ? Any comment is welcome.
