Is there a way to get a node ID from a URL without an access token?

I have built a simple JS extension to pull the node ID from public Facebook pages using the DOM HTML. It would be better if I could make a graph api request to fetch the node id with the URL of the page so that I don't have to wait for the DOM to load. It will also work regardless of the page structure. Any suggestions?

Additionally, I would like to be able to query the page id without an auth token. This page suggest that should be possible.
