Is there a development API available for Zemanta?

is there a developer api available? I love what zemanta does for my blog, but I want to explore how I could use it on a site with tons of archived data. Particularly for a sites like http://www.biodiversitylibrary.org/ http://www.biodiversitylibrary.org/ and http://eol.org I'm working with some of these organizations, and I think your service would be very beneficial to users; they hit a results page, and then Zemanta would start popping up related articles and pictures from the web, maybe even pics from Flickr. We really want to push user experience with our new Open Source efforts, and Zemanta would take us in that direction.

Thank you
Phil
