I have a small business in doing repairs and I'm willing to take bitcoin, but i was wondering if there is a site that aggregates all the bitcoin exchange prices so I can get an idea of what price to charge in bitcoins to avoid the day to day volatility. Yes i know i can use bitpay, but I want to be able to just take bitcoin myself and come up with my own merchant rate that i choose and feel comfortable with.

bitcoincharts.com is one of the more popular ones:
BitPay provides an exchange rate quote:
You can place my bitcoin price table on your site: http://coinrepublic.com/website-tools/
I have written a Python program that looks at bitcoinchart's API and finds the median price. This might be useful if you wanted to automatically adjust prices in an online store.
import urllib2 import json def average(l): return sum(l)/float(len(l)) #From fraxel def median(mylist): sorts = sorted(mylist) length = len(sorts) if not length % 2: return (sorts[length / 2] + sorts[length / 2 - 1]) / 2.0 return sorts[length / 2] currency = "USD" url = "http://api.bitcoincharts.com/v1/markets.json" result = urllib2.urlopen(url).read() prices = json.loads(result) def by_currency(symbol): def f(ticker): return ticker['currency'] == symbol return f def by_volume(min_volume): def f(ticker): return ticker['currency_volume'] > min_volume return f def get_price(ticker): try: return average((ticker['ask'], ticker['bid'])) except: pass print ticker raise Exception("Can't find price in ticker") # Avoid prices in wrong currencies prices = filter(by_currency(currency), prices) # Exclude small exchanges prices = filter(by_volume(100), prices) prices = map(get_price, prices) single_price = median(prices) print single_price
