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.

They want a login before even giving a key. Can you summarize their features? What data do they show? We offer real-time data to clients. Real time is hard to beat.

Real-time level 1 and level 2 price feeds Time series historical data; tick, n-minute, daily bar database Various REST APIs to build CMC like web displays

> What is simpler to read quickly, 0.000123 or 1.23e-4? 0.000123

And between 0.00000123, 0.000123, 0.0000123 you are sure which one is which without effort? I can't

When they’re aligned vertically, say as part of a table, then leaving the zeros in makes it much easier to read.

what CMC does is what everyone does, i think it's the standard method. From your frontpage it seems u already have those values somewhere

We have many values, but if we think they may mislead people, we don't show them. It is our ethics. We do not want to do what everyone does. We will show more coins when we think we can show non misleading data. It's a question of trust. We want happy visitors and happy clients. We want to earn their trust. Thanks for a lot for using our data on coinzaa! We would appreciate a link, but only if you feel like it.

i have 2 links. one in the frontpage and one in the footer . I also run an ad banner to your site

Thanks! So generally the same things we currently already have. Don't they have full market book data? We are wondering if we should do that. It could be a separate subscription plan if there is enough interest.

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.

wow 2 links, we didn't ask that much :-)

I really appreciate. We will work on having the percentage change online for you in the API as soon as possible.

Not sure.

Check http://cryptomarketplot.com/accessible-index.html : the numbers are also aligned, and in less space that it would take if 5.744e-5 was to have all its leading zeroes.

This is really cool, great work!

I am one of the developers of Blockmodo. It offer realtime data streamed directly from the exchanges via a WebSocket API. Alternatively, you can also go through our REST API as well to get this data.

Data can be streamed aggregated or if you choose, you can also stream and poll the data on a per-coin basis. For example, if you want the aggregate price of Bitcoin you can do that but if you want the price streamed of Bitcoin for BTC/USD for Bitfinex, you can do that as well.

In addition to the price, we offer full streaming and REST data on:

- Realtime news on each coin. Our backend also detects bot generated articles and excludes those.

- Realtime community posts across different sub-reddits, forums, etc

- Realtime social posts from the developers of each coin (twitter, etc).

- Realtime code checkins from the developers across multiple repos segmented by the coin (github, etc).

- Full coin profiles (name, website, telegram urls, etc).

We do this on over 2700+ coins for developers and terminal makers across 100+ exchanges. You can explore the documentation here:

https://blockmodo.com/docs/api

How can I see it in action?

You can see it in action here by visiting our front page:

Another terminal app that is connected to the network is CoinHub for iOS which you can check out here:

3.436k is a much simpler way to remove the zeros, and actually includes one less character.

Yes for BTC, then for something 10x that 34.36 start looking not as good. We could make an option for people who prefer regular numbers. I will add that to the feature requests.

I think I’ll look back on this day in the future and smile:

At one point the crypto bulls were so bullish that they worried they wouldn’t easily be able to fit in enough zeroes for the price without using scientific notation...”

During tests, we found it was better to let people chose. You can use whatever method you feel more comfortable with. Sometime usability and security go in different way. We could do HSTS but if you took time to type http:// maybe you really want http not https

Why is it better to let people choose? That implies there is a downside to https:// or a reason some people prefer http:// -- can you elaborate? If you type just the domain name you get http:// by default, which, in my experience, is how most people type in site URLs.

People have their reasons, we respect that. But a default to https, why not? It seems reasonable to me.

I am not sure on how to get https:// by default while still supporting http:// for people who prefer it. It may take some advanced 302 redirect.

We will investigate and see what we can do there. Suggestions are much appreciated.
