title: To build an App for an Internet site without its API and Schema
body: <p>I was asked to build a control-system for a Ebay-like Finnish auction-site <a href="http://translate.google.com/translate?prev=hp&amp;hl=en&amp;js=y&amp;u=huuto.net&amp;sl=fi&amp;tl=en&amp;history_state0=" rel="nofollow noreferrer">huuto.net</a>.
  The system would reopen closed auctions by a specific rules. It would be completely external from the main site, running at an external website.</p>
  
  <p>The site is however unwilling to release its API and Schema. I know no way to build such a system without knowing its API.</p>
  
  <p><strong>How do you build an internet site without its API and Schema?</strong></p>
