The API went down today. The error is '501 Not implemented'. I need the API to make use of this pool; has something changed?
From the top of the webpage :
- API is disabled due to high DDoS attack. Will add some limitation per account and reopen it soon.
Bummer!
I also cannot mine on the pool without the API being active.

Sorry.
There was some serious DDoS like attack through API request.
Now it's open again with some request rate limitation.
I'll not close API feature again without notice.
Sorry again.
