This is an Intrinio Ruby SDK for Real-Time Stock Prices. It provides real-time stock prices via a two-way WebSocket connection. The Intrinio Real-Time Feeds uses the WebSockets protocol to push stock price quotes to clients in real time. The Intrinio Websockets API will send you the last recorded IEX bid/ask/last quotes, even during off-hours. So you will notice that the first quote update will come through immediately upon connection, and it will have an older timestamp. All quotes afterwards are live updates. Intrinio is a financial data marketplace that is restriction-free with self-sign up, and chat support.
Mapbox has completely revamped the pricing model for its API and SDK portfolio. The company has increased its free tier, and transitioned to a completely pay as you go model. Volume discounts apply, and automatically activate as a user's consumption grows. No commitments are required.
Over the past few months at PW we've noticed steady increase in the number of mentions of Data as a Service (DaaS) and this trend looks to continue. Our first post on the subject was by a guest author Pete Soderling who introduced us to the concept and discussed pricing models. Then we continued the theme by posting about a partnership between a stock data site and an open data platform, working together to deliver a stock historical data API. The latest big move in this area sees NASDAQ creating a Data-On-Demand service accessible through a Web API.
