This is what Strip Chat told Paul from NiftyStats. So start sending them an email to that address, so they see there is an actual need for them to provide an API to Nifty.
"the guys at Strip Cash asked us to tell everyone who wants to download stats from their program in Nifty Stats to contact them directly at
[email protected]
So they know if there is a demand to make something on their side to make it work again in NS."
