We've been working hard on the new api. The first revision is done and ready to use. The previous restful interface for adding data will still work, but is deprecated. I think you will find the new api simple and powerful. It is currently in beta so please let us know if anything doesn't work as expected (or if the docs are confusing). I can't wait to see what you guys come up with, so please post your apps on the forum.
