I am glad to announce that the API is finally ready.
You can create offers, cancel offers, look up your balance and more via the new API. However, withdrawing and depositing has to be done manually (this might change in the future).
So, don't hesitate and start automatic trading without fees now
Here's the documentation:http://mysolidcoin.com/p/main/api.htm
You get 1000 api calls per hour. I think this should be enough. After that you will receive a message telling you how long it will take until you get another 1000 api calls.
