I have gotten a lot of requests for Flash API's so I thought I would list some of the ones I have done here.

Gazo (http://www.gazo.com/)
Mindjolt (http://www.mindjolt.com/)
Yepi (http://www.yepi.com/)
Gameshed (http://www.gameshed.com/)
HighScore (http://www.highscoregamers.com)

There are also some non-public ones as well, so if you need something specific or have any questions, let me know!
If anyone is in need of one listed, or you need one for a sponsor, send me a PM and I will see what I can do.
