I recently released FFFFOUND Desktop, this AIR app uses a home-made API that I'm open sourcing today. The code is hosted on Google Code and is available via SVN, I also uploaded a zip archive if you prefer.
You'll find the (asdocs) docs in the repository and in the archive.
By the way, I love feedback. If you use it: please share!
Also, if you need examples on how to use it, ask. I think the sources are self-explanatory but I might be wrong.
A few important things (also posted on the project's page):
- For now, this API will only work in AIR projects because ffffound.com's crossdomain.xml is too restrictive. I've contacted them but at this time they don't want to change it.
- The API relies on FFFFOUND's RSS feeds but also on the site's pages' HTML, so some functionalities might break at any time without warning. Use with caution.
