How does webkit / chrome WebInspector Resources Inspection work?

I always want to know how resource checking works in webkit / safari / chrome WebInspector.

Should the browser provide its own BPI or something for javascript to display a list of requests and their time frames, what is called a binary API? Can I use the same API to write the Chromium extension?
