The Google AJAX Search API was just released by Google a couple of days ago. Anyone with their own blog or website can freely register to obtain an API Key. The usage method is very simple, involving JavaScript scripts and CSS style files called in the Header domain. The official CSS file can be downloaded locally for modification and editing, allowing you to customize more elements according to your preferences. As for the JS script, I (volcano) have conducted a simple analysis. If you're interested, you can visit the official page to get your own Google AJAX Search API Key. You can check out a simple Demo that I made casually to see the effect.
