title: JSON search API for finding Android apps (on Android Market and elsewhere)?
body: <p>iTunes offers a JSON API for searching against app names (e.g., find all apps named, "Yelp").</p>
  
  <p>We can't seem to find the equivalent for Android Market or other Android marketplaces. Does this exist?</p>
  
  <p>The ideal API would let us search for any Android app, even if it's listed on Amazon and not on the Android Market.</p>
