The ipernity API allows creating applications that can do whatever you see on the ipernity website and even more. For example: import new documents, tag a photo, create an album, search in your documents or those of all the members...
Click the "Track this API" button on any profile page and never miss an API update, new app, or breaking news for that API again.
There are no source code libraries or how-to links for Ipernity. If you know one why not add it?
I just discovered this site (through its api listing here) and I'm really enjoying the experience the site offers. Very flickr. I'll report back when I get into the API more.
