Can I use the Rumpus API to make my own software/websites?
It is definitely a violation of our Terms of Service to directly access or manipulate the data being sent to our Rumpus and BscotchID APIs. Only our official clients (our games, websites, etc) are allowed to access our APIs.
That said, we do believe that opening up some access to our services is good for the community. To that end, we have an official API, called Rumpus Community Edition, expressly for the purpose of letting you build your own stuff.
