title: Is there a Wikipedia API just for retrieve the content summary?
body: <p>I need just to retrieve the first paragraph of a Wikipedia page.</p>
  <p>Content must be HTML formatted, ready to be displayed on my website (so <em>no</em> <a href="https://en.wikipedia.org/wiki/BBCode" rel="noreferrer">BBCode</a>, or <em>Wikipedia</em> special <em>code</em>!)</p>
