Have you evaluated cryptoquote.io? Take a look at their real-time level 1 and level 2 websocket APIs. They seem to understand market data and have navigated the non-standard connections to cryptocurrency exchanges well.
Can you summarize their features? What data do they show?
We offer real-time data to clients. Real time is hard to beat.
We are prioritizing in new features people who want to do a CMC like web display but are not comfortable with coding.
We want non programmers to get our data without depending on the JSON or other complex stuff. Something light and simple.
