A better question to ask, I think, is what information is not available readily. Meaning, not in a machine-readable format, not complete, not up to date, not free, not from a reliable source, etc. Something that I found this to be true for is basically every List_of_* Wikipedia article, the machine-readable format especially. But then if you look up the same information on WikiData it either doesn't exist or it's massively lacking in one of the points above.
