Bitcoin's real-time Buy and Sell price API What is the API to get Bitcoin's real-time Buy price and sell price on my site? and how can get it from to implement in my website developed in PHP.
Bitcoin does not have one single buy and sell price. Bitcoins are exchanged on many different exchanges, each keeping track of their own market price.

However, BitcoinCharts.com has a useful API that summarises many of the largest exchanges according to their trading volume. You could use that to display the Bitcoin price on your website.
