title: Best/Most Comprehensive API for Stocks/Financial Data
body: <p>What is the most recommended free/public API for accessing financial market stats and stock quotes (preferrably real-time quotes)? I'm not too picky about how it's exposed (SOAP, REST, some proprietary XML setup, etc.), as long as it's got some decent documentation.</p>
  
  <p>I'm planning to build a simple web dashboard in PHP with some basic data (basically a quick-n-dirty homepage), but may want to grow it into a full blown web app eventually. Any thoughts?</p>
  
  <p>As I find some, I'll post a list here (feel free to comment if you've used any of them before):</p>
