Yeah it’s still there and it’s working sorta, I messed around with it a couple months ago and a lot of their examples are broken out-of-the-box BUT…they say they’re working on pushing some updated examples. Jump into their forums and start asking around, they’re pretty responsive. I, on the other hand, have just went to Coronium. You may also want to check out api.shephertz.com/ I haven’t used 'em but they seem about the same as photoncloud.
Good luck!
