Where to find cryptocoins current price How can I find API (json data) for cryptocoins current ask/high/low/average price. Is there any website that provides that ticker information for all coins. 

For example BTC/LTC ticker info is available in 
https://btc-e.com/api/2/ltc_btc/ticker
I use bitcoinwisdom which in the market section has multiple exchange ratios for BTC/LTC/DOGE and for fiat money like USD/EURO/RUB.

Another option is this page in cryptocoincharts which also has many market prices for cryptocurrencies.
