title: Github API OAuth token validation
body: <p>Is there any way to validate my OAuth token for the github API? By 'token' I mean the one I get after the user has logged in to my website. I store it on the client computer using cookies, but just checking if there is a token is not enough: I need to actually check if the token is valid or not. Currently this requires me to make a request for information and then catching the errors. However, this is really damaging my rates and also my load speed as the github API is <em>sloooow</em>... I am using Node.js, express and the <a href="https://github.com/pksunkara/octonode" rel="nofollow noreferrer">octonode</a> library.</p>
  <p>I tried looking at the github API docs, but they are minimal. Maybe this is to do with OAuth.</p>
