Yes, it is sad how some glee from failures.

I will keep on working, crash or not, because I like what I do.


All I could see on this website were the tweets and things I don't really care about. We seem to have very different goals.

But after talking, I'm curious to see what kind of market data they have. I asked for a small sample.

I am still waiting for reply from electic.


Piggy backing rubs the wrong way, but sometimes there is interesting content.

Personally, I would challenge the piggybacker to show me something.

Talk is cheap.


We already have that data. We don't show it because we want to filter out bad data!!

Let's take an example: illiquid coins, like for new forks.

Look at the prices quoted on every exchange: you will often see huge differences. Because on some exchange, you can only buy the new coins - not sell them. So the price is high. On the exchanges where you can buy and sell, the price is low.

We think that's scammy. We don't want to list these coins or that information.

We are working on ways to do that, but extending over the top 50 is not very high in the priority list. There are even coins from the top 100 we are not comfortable showing in the API. We just hope they won't ever make it to the top 50 on our frontpage :-)


Huh, thanks?

But that's a bit different from what we are doing.

We concentrate on hard numbers and privacy. You seem to focus on news and community. And it seems to me your API requires a login. Also, your homepage looks nice, but I don't find on it the information I want - cold hard number, graphs! However, I find plenty of stuff I do not want - like twits?? I don't want twitter or anyone else to track me.

Your site looks nice, but I think we have very different goals.


Different experiences I guess. We do not require a login. You can use the API without a key.

We actually started of with the price. Our goal was to be as low latency as possible. We have all the stats like price, histograms, market cap, etc in there. Most of our infra is keeping number stats on coins and maintaining profiles on them

However, the days of price and marketcap are over. We are seeing that feedback come from larger customers. They want to see code checkins, they want to see what's happening in the different sub-reddits, they want to keep up with what the team is tweeting. All those feeds are important to give you a holistic view of a coin and the market in general.

Anyway, happy to help and share whatever we can. Feel free to drop us a note.


Marketcap is totally overblown, I agree! We talk a bit about it in our FAQ. And I'm sorry, I assumed I needed a login on your site because I just couldn't find a way to quickly send a query.

Most sites hide they API behind a login and require a key and signing a TOS. That's not public. Our public API is totally public.

I'll be happy to get in touch, because we are starting with the same goals as you: low latency, and stats.

To see what you have achieved there, can I get a sample of your raw data? Like the first 2 days of december, showing at least the bid/ask/last per exchange, per pair. More if you have more.

It should be stale enough and a small enough window to not cause problem extracting or be of much value. Any format you want is fine. You email me a link to the dump and I'll have a look.

I must say I'm very curious now.


Thanks, I will see how they do it.

I don't want registration or even cookies.


We could fix that, but I kinda like TOR.

Keeping it in all caps (like when it was just an acronym) puts it forward.

We want to emphasize our support of privacy.


Fair enough if that’s what you want but if you just make up how you name things it’ll confuse people. You wouldn’t spell PGP like PgP either.


I don't want to confuse people!!

Ok, we'll fix that.


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


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.


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...”


I am indeed bullish on crypto, but the decision is driven by facts, not by passion.

The fact is the price range vary too much, even in the same scale (say BTC/USD vs XRP/USD), so we decided to have 5 characters for every price.

That requires the use of scientific notation.


Percent change, you mean you want the equivalent from the original CMC JSON:

        "percent_change_1h": "XXX", 
        "percent_change_24h": "XX", 
        "percent_change_7d": "XX",
We can add that, but we want to use fixed points in times, to avoid floating periods comparison.

Here is an example for the change in 1h: it is 10:45 AM, so do the average for 10AM, do the average for 9AM, see the percentage change.

A bad method is to average from 10:45AM to 9:45AM, average from 9:45AM to 8:45AM then report the percentage change, because if there was a big change at 9:30, and just one, then the coin is stable, it will have decaying effect on the percentage change. You will see it moving, while the coin has stabilized! To me, that's wrong.

Coinmarketcap was doing the latter. We can support that, but you should consider switching.


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


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.
