API News

7th January 2011 -- We've added some new parameters to our responses. Among others you can find "relevance" for links (we used to do just "confidence") and "entity_type" to determine which kind of entity it is (a person, book, place...)

You want to integrate Zemanta in your custom CMS? Here's how: Zemanta Javascript SDK!

Easy SDK

Here's what one developer had to say:

We fell in love with Zemanta as soon as we laid eyes on it, and after a chat with their team we found that their SDK was so easy to use that we had a prototype Joomla! plugin in just a couple of hours. Now Joomla! users can quickly and easily add related articles, rich media, in-text links and semantic tags to their blog posts with just a few clicks.
