This ticket is for compiling the data that will be output at XTools: Articleinfo (see T157602). This ticket should be considered done when there is a way to view the data over the web. The output should be super basic though, just var_dumps or simple tables, no real views or nice UI.
Compare the data against the old interface (http://tools.wmflabs.org/xtools-articleinfo/?article=Test&project=en.wikipedia.org) to see if it lines up, but bear in mind there are known bugs with the old version. Testing is probably best done on smaller pages so that you can manually check for accuracy.
Known bugs with Articleinfo can be found in the GitHub issues and on the Phabricator board.
