I was hoping for some raw json. Trying to avoid parsing the html.

EDIT-- Found json sources:

EDIT2-- This is not what i was looking for but may help others:

Change bitcoin to the coin you like. 7d, 30d, 90d, 180d, 365d are all valid periods. Do not be too surprised if hitting this non-public api gets you IP banned.
