API Keys are free, and highly recommended. They increase your rate limits, and seriously decrease the chances your server will be blacklisted if we have a problem with something you're doing. Make sure to provide valid contact information, else your key WILL be disabled.
To get a key, join this server and run the command /apikey create in any channel. The response will only be shown to you. You can have up to 3 keys at a time. If your usage of the api goes beyond our current rate limit restrictions, please contact Donovan_DMC.
