Flickcurl is a library for implementing the Flickr API in C. This library supports the entire Flickr API, including functions for browsing, searching, and uploading photos and videos. It comes with a program called flickrdf that turns a photo's metadata, tags, machine tags, and places into RDF triples descriptions.
Bryan Parker founded ImageFly out of necessity: "To be honest, I was fed up with having to bounce around between image libraries when I was hammering out a project. It seems like it was GD one day, RMagick the next, and something else the next." ImageFly exists to simplify image modification. The ImageFly API grants developers many image editing tools within web properties and applications.
We all know we can search web pages for text, but many services are looking to go above and beyond with features like location and face tagging. The big downside to these features is that they rely on end users have to manually enter in the appropriate data. Really, when was the last time you tagged all the people in the 200 photos you just uploaded to Facebook? To help automate the process of face recognition, face.com have just opened their API.
What makes a trip to a restaurant a great experience is not just the fact that they serve delicious food and good wine, but it has a lot to do with the atmosphere and overall 'vibe' of the place. Of course, a 'good vibe' means different things to different people (some like it chilled and some like it loud and bustling), so imagine how cool it would be to be able to browse through dining options based on the exact atmosphere you're looking for. That's what Hoppit is all about; finding restaurants by atmosphere. Hoppit's API provides access to this handy functionality.
