Add exchange field for websocket trade message

looks like all websockets are down

I'm creating a chart from history and suspect http://coincap.io/history/1day/BTC prices are in the wrong order - that is flipped regards to time. Week and month looks correct when i compare it to coinmarketcap etc.

First time doing a history request is slow.

time curl http://coincap.io/history/180day/BTC

First try responded in 4.341 seconds.. Additional tries are usually very fast.

Would be awesome if you could improve on this. Thanks for a great API !

Have you considered open sourcing the API ?

Maybe more people could help out.

For
http://coincap.io/page/ETC

Add url to homepage, social media, etc.

Could also supply a url to history or markets for that coin.

I had to figure out timestamps are in milliseconds by trial and error until history/365day spanned a year.

Hi,

I am working on new project and i would like to know is there limit on accessing API ?
thanks

API suggestion:
Add support for "limit" - to limit the number of returned values.

E.g:
http://coincap.io/front/?limit=10

Should return the top 10 coins.

Socket API is not firing Trade message? What is the interval for update?

http://coincap.io/history/eth

Is giving a 'null' as response, while BTC works. There seems to be an inconsistency which coins work an which don't

Hi, dears I sent 0.04403492 BTC to 1A1kEfY1dnfTF9x3oNQZVAVnJHd8kRwBGs for buy DASH, but the funds not are into my DASH Wallet yet

Calling: http://coincap.io/history/bitcoin

Returns a top level field marekt_cap.

"volume" for BTC history is 0 in many cases. Is this correct?

See:
http://coincap.io/history/BTC

I have copied this exactly in my index.html file with correct path to socket.io.js

<script src="yourlibpath/socket.io.js"></script>

<script type="text/javascript">
    var socket = io.connect('http://socket.coincap.io');

    socket.on('trades', function (tradeMsg) {
        console.log(tradeMsg);
    })

    socket.on('global', function (globalMsg) {
        console.log(globalMsg);
    })
</script>

The problem I have is the response

{code: 0, message: "Transport unknown"}
code: 0
message: "Transport unknown"

How is this fixed?

My wallet resent btc to buy DOGECOIN by blockchain, but I can not received Dogecoin from you, yet. Why?

Currently it's impossible to know whether the cryptocurrency is a token or not, is it planned to have a param for returning only tokens from the API?

I love your site, but every time I open up the screen I'm very happy until I realise that the currency selector has gone back to USD instead of EUR. Could you please track this. Thanks! :-)

Is there a spec for the way coincap names the images at http://www.coincap.io/images/coins/
For example: http://www.coincap.io/images/coins/bitcoin.png returns the proper image, but some coins are not following this convention. For example Ethereum Classic coin image can be found at http://coincap.io/images/coins/ethereumcla....png

I've trimmed the coin name but this is not enough. Any help would be appreciated. Thanks in advance.

For some coins the coincap.io/history/:coin works fine but the coincap.io/history/:period/:coin API returns empty arrays.

Affected coins:

• Basic Attention Token (BAT)
• Bytecoin (BCN)
• Golem (GNT)
• Gnosis (GNO)
• possibly others

coincap.io/history/1day/BAT example response:

{
  market_cap: [ ],
  price: [ ],
  volume: [ ]
}

It continues to show 145 while it is 139 now and hasnt changed for more than a few days

http://www.coincap.io/history/BCH returns null.

Hi,

I was listening to socket stream for a while but didn't receive any Modum (MOD), Red Pulse (RPX) changes. Can I somehow get these coins from stream or is it only possible to get them from API calls since they are not in Bittrex/etc exchanges yet?

If you request http://coincap.io/history/1day/XLM, you'll see that the the time point before the last one for prices is 1476416950000, which is 14 October 2016. The points before that is also delayed. The last point is 1510755221928, which is up to date.

This delay, as mentioned #48, also occurs for other coins.

Hi,
First, thanks for your hard work.
Just there is a question. Since I have tried the API, "http://coincap.io/front/?limit=1", but this still cannot work for me to get what I want, is there any way to get some data instead of all data???

Thanks for your answer.

1. Small typo in docs. You have:
   http://www.coincap.io/page/:coin

Should be without the colon:
http://www.coincap.io/page/coin

1. The following coins are not loading from this API call:
   ETC, OMNI, REP

https://blockchain.info/tx/5ccea15ca9de8769c806d84df0f2803dc2fa28610de12590ce6b0f0320bbfbf5
I did supplied BTC, but I could not received Ripple (XRP)
please, help me

Does the api have an https option? Or do you only have http?

When i call the API from an ionic app, with ionic serve it shows this error.

XMLHttpRequest cannot load http://www.coincap.io/history/1day/ETH. Origin http://localhost:8100 is not allowed by Access-Control-Allow-Origin.

Hi.

I tried to use this URL: http://www.coincap.io/page/ETH

The status i 200, but I only get an empty object as a response. Works fine with BTC.

I am trying to access the JSON object of Ethereum currency, using : http://www.coincap.io/page/ETH
However, JSON object that is retrieved, shows Bitcoin price, why ?

Has anyone had any similair issue ?

I have a bot that pings /front and displays some data.
The problem is the data is stale and has been for days.

I have tested with postman on different devices/IPs and the same stale data is displayed.

"price" is correct and updated constantly. "price_usd," "price_btc," etc are not updated (static).

I had an issue with a Coincap.io transfer. I tried to transfer https://blockchain.info/tx/8c49208c2c3866384da6be5c7779905508f29050b4eabcc114a808e6dd5395fa money through Coincap.io to get peercoin and it never came through. I would like the bitcoin in this transfer sent back to me. The PPC receiving address isn't even in the PPC blockchain yet so CoinCap has made attempt to complete the transfer PTnobWa3RBUrZwdWJwk1Ba5tKr6Si8CrYt. Because it too a long time and nothing happened I would just like my Bitcoin back.

Any plans to include Bitcoin Gold (BTG)?
See:
https://bitcoingold.org/
https://coinmarketcap.com/currencies/bitcoin-gold/

When calling: http://coincap.io/front

Something like this is returned...

[
  {
    "shapeshift": true,
    "position24": "1",
    "position": "1",
    "short": "BTC",
    "long": "Bitcoin",
    "time": 1445264668141,
    "price": "264.416",

    "published": false,
    "vwapData": 266.3100005172462
  },

  ...
]

What's the difference between vwapData and price? They look very similar across all of the coins respectively.

Hi there,

Thank you very much for this project! I embedded the script to a html page,

It's not showing. What did I missed please? Any help will be appreciated! Thank you so much!

Best Regards,

I've tried accessing the endpoints in Main Map and none return the thumbnails of each currency.
Ideally I'd like to pull currency info + logo in one call. Does this exist?

Hi,

I can't access to : http://www.coincap.io/page/mycoin, returning that error : {"status":0,"message":"Database::getDynamo(): Error: ResourceNotFoundException: Requested resource not found","timestamp":1503957209137}

Is there support of other currencies like EUR/GBP or will it be added?

We're using the API in https://github.com/loon3/LTB-Companion-Wallet which is a Bitcoin + Counterparty Assets wallet. Currently assets are not filterable so we also get Omni, NXT assets and other prices that are irrelevent to our application.

Request: Please make assets filterable by the meta-protocol they are built on to allow efficient requests without the unnecessary information.

Hi,

Are the USD prices in historic data, for example a year back, looked up against BTC/USD of those dates and times?

In other words, are the USD prices accurate for every timestamp for every coin?

1. is there a way to get all coins and which exchanges they are listed on?

2. I could not find which exchange's data is included in the api, i listened to the socket.io api for about an hour and could only see bittrexx and kraken trades.

3. is there a way to get icons for all the coins?

4. when is v2.0 of the api suppose to release?

5. what are the limitations of using this api, are we expected to have a rate limit when calling the apis?

6. Is t here a better place/platform to ask questions in the future than having to fill out issues on github?

Thank you for providing a very valuable service

Most notably:

• http://www.coincap.io/history/1day/bitcoin
• http://www.coincap.io/history/7day/bitcoin

Front for specific coin returns html, not json

E.g:
http://coincap.io/front/BTC

as my form to add new coins in the coincap ??

The documentation suggests connecting to http://socket.coincap.io, which used to work, but now that address doesn't seem to respond, and instead connecting to http://coincap.io works.

Is that change permanent? Worth updating the docs if it is.

Thanks!

When requesting history data through a GET request on http://socket.coincap.io/history/1day/BTC, the data is indeed one day, but we want 1 day data up till now...

Is there a way to get this data up till the time and date of the request or should we consult another API. The candlestick chart on http://coincap.io/BTC is capable of fetching this data so why not on the API?
