Intrinio (http://intrinio.com/) currently offers the least expensive Real-Time and REST API for US stock prices.

You can access it via WebSocket, or Web API. No other firm currently offers this data via WebSocket which is especially helpful as you only need a few lines of code to implement. Additionally, Intrinio's customer service chat support is live practically 24/7.

The real-time feeds can be found here: https://intrinio.com/marketplace/data#?category=prices&sub_c...

The REST API for prices would be best in this feed: US Public Company Financials (https://intrinio.com/data/company-financials)

This blog will tell you everything you need to know to get started using the real-time API: http://blog.intrinio.com/stock-prices-from-intrinio/

It's not the least expensive. https://www.alphavantage.co/ is free.
