Developer API:

The developer api is made out of events. They're 3: BlockedCommandRanEvent, PlayerContainsBlockedItemEvent, PlayerContainsBlockedPotionEvent.
Their name explains everything what they do.

If you call them, try setting a priority also, because the plugin's running them also, because I am lazy man :D .
