• original_url and final_url. Funkspector follows redirections, here are the original URL given and the final one after following the redirections.
• scheme. Like, "http" or "https".

• links. Organized in raw, http.internal, http.external and non_http.
• root_url. Root url for the given URL. For http://example.com/about it will be http://example.com.

Error response

In case of error, Funkspector will return the original_url and the response from the server:

case Funkspector.scrape("http://example.com") do
  { :ok, data } ->
