EDIT: [quote:ru7vsmbh]The API Tools are a set of classes you can add into your game to track statistics, earn revenue and add features that integrate into the newgrounds community.
With the API you can:
Earn revenue no matter what site your project is hosted on.
Track how many views your game has had across the entire web.
Track how many users click links to your web sites from your game.
Control what sites your game can be hosted on.
Add score tables to add a sense of competition in your game.
Add unlockable medals to add more replay value to your game.
Enable your game to save data that can be shared with other users.
The API is currently available for:
Flash 8*
Flash CS3 or better
Flex Builder/FlashDevelop
* Limited support for ActionScript 2.0
