title: What would be the most ethical way to consume content from a site that is not providing an API?
body: <p>I was wondering what would be the most ethical way to consume some bytes (386 precisely) of content from a given <em>Site A</em>, with an application (e.g. Google App Engine) in some <em>Site B</em>, but doing it right, no scraping intended, I really just need to check the status of a public service and they're currently not providing any API. So the markup in <em>Site A</em> has a JavaScript array with the info I need and being able to access that let's say once every five minutes would suffice.</p>
  
  <p>Any advice will be much appreciated.</p>
  
  <p><strong>UPDATE:</strong></p>
  
  <p>First all thanks much for the feedback. <em>Site A</em> is basically the website of the company that currently runs our public subway network, so I'm planning to develop a tiny free Android app for anyone to have not only a map with the whole network and its stations but also updated information about the availability of the service (and those are the bytes I will eventually be consuming), etcétera.</p>
