Just a warning that the Cryptsy public API is completely broken; it is returning the exact same stale data each time. If you're using software which fetches order book and market data using this API, you're gonna have a bad time. It was because of a loss that I incurred that I noticed the problem.
I have personally observed the same data returned from
http://pubapi2.cryptsy.com/api.php?method=orderdata (MD5 ea6f1a947a1bb124e11044198c809447) for about 36 hours, but I expect that the data is from at least a few days ago, possibly even more than a week (this is meant to be a live API!)
From a Linux/BSD commandline the following will fetch the data and report the MD5. Try it yourself:
wget -O - "http://pubapi2.cryptsy.com/api.php?method=orderdata" | md5sum
My ticket reporting this issue was open for a couple of days, then it was quietly closed without any response. You can draw your own conclusions from that.
