Rather predictably hit the API rate limit :-)
EAPI:Rate limit exceeded
Can you specify what the rate limit is? Bitstamp is 600 request per 10 minutes, ie. 1/second...
My bot is throttled, so just need an accurate quantity. Thanks!
Your earlier suggestion on the API documentation is noted.
The basic API rate limit is 1 call every 5 seconds. You can do faster bursts up to 10 calls, but then you'd need to follow that by a 50 second pause before you could resume the 1 call very 5 second rate. If you get locked out, it's for 15 minutes.
For really active traders (including those who want to market make with us), we can offer much higher limits. Anyone interested in this should contact us with a support ticket.
