Most bitcoin exchanges have API that can be used to grab market data. The price can vary from exchange to exchange but you can use places like coinmarketcap to see the volume for each exchange. Generally the exchanges with more trade volume are a more accurate representation of the current prices. I tend to look at Bitstamp and BTC-e for BTCUSD price since there is less bot volume and wash trading on those sites.
