I'm no big programmer or whatever, and only an efficiency user, and in that case, the site doesn't work. When I try to use the craft calculator, it says "Invalid API key". So, as I'm a good boy, I went back to the application, and made a new one (just in case, you know), and efficiency won't register it because "API key is invalid, or API is disabled".
Considering that I just used the official site to make a new key, I'm guessing it can't be invalid, which means the API is disabled.
Thought you'd want to know it...
EDIT : it works again, then it's off again. I'm not sure where the issue is after all.
