Google "auto answers" what are they called and is there an API? : <p>When you query google for information, google itself usually offers an answer before you click on any site.</p>

<p>For example
"Who is the richest person in the world"</p>

<p>Google : "Bill gates". I am wondering A: what this service's name is. And B: if there is an API we can use</p>
