Link to docs next to every API call link

@matthieu I was thinking this might not be a bad idea to make part of the API. What if you threw something like this in your json response:

'doc_url': 'http://dev.blockcypher.com/reference.html#blocks',

I've never seen this before, it might be a bad idea.

Sorry, not a huge fan :) JSON is great for human readability but it's still a data format, I'm not sure I want to increase the side for every calls just for this.

Fair enough!
