Historical BTC data in JSON As of now, the only API I can find that serves historical data is https://blockchain.info/charts/market-price?timespan=60days&amp;format=json. It only uses USD, and I need to serve non-USD data. My google-fu is failing me, does anyone know of an API that serves historical data for more than one currency? Preferably a currency I can specify as part of the API call.
You could also try the Blocktrail API: https://www.blocktrail.com/api. 
They are new on the scene but their API can be quite useful. They have a node.js API as well as PHP, Python, CURL and jQuery. It doesn't track prices though but hope it can be of help some other way.
