It really depends on what you want? Do you just need to monitor the price, or need API to do something more?
for the former, bitcoinchart gives a at-a-glance price comparison: http://bitcoincharts.com/markets/currency/USD.html (you can also change to other currencies)
Topic: What is the most reliable source for current price feeds? (Read 729 times)
Bitpay will is no longer pegging to mtgox (http://blog.bitpay.com/) and I think mtgox prices are going to cease to be as reflective of the market as they have been in the past (assuming suspending dollar withdrawals negatively impacts their volume). I've been using bitcoinity and clark moody for mtgox price feeds. Is there a service which aggregates the several exchanges with level 2 quotes plus time and sales?
Thanks in advance
