BitcoinAverage API integration examples

Examples of how to integrate with our API in various langauges

BitcoinAverage Packages

We have published our own npm and pip packages that do the heavy lifting for you (authentication, handling requests, remembering the full urls).

NPM Package

This library enables quick and easy access to our Bitcoin, Ethereum, Litecoin, Ripple and other cryptocurrency exchange rates.

Install

npm install bitcoinaverage

Setup

Get your public and private keys from our website and you are ready to run these examples.

const ba = require('bitcoinaverage');

var publicKey = 'yourPublicKey';
var secretKey = 'yourSecretKey';

var restClient = ba.restfulClient(publicKey, secretKey);
var wsClient = ba.websocketClient(publicKey, secretKey);

Ticker Data

The response received by https://apiv2.bitcoinaverage.com/indices/global/ticker/BTCUSD.

The symbol_set can be one of: local, global, crypto and tokens.

The symbol can be any pair from our Full symbol list

var symbol_set = 'global';
var symbol = 'BTCUSD';

restClient.getTickerDataPerSymbol('global', 'BTCUSD', function(response) {
    console.log(response);
}, function(error){
    console.log(error);
}) ;

Exchange Data

All price data from single exchange

restClient.perExchangeData('bitstamp',
    function(response){
        console.log(response);
    },
    function(err){
        console.log(err);
    });

Data from all exchanges for one symbol

restClient.allExchangeDataForSymbol('BTCGBP',
    function(response){
        console.log(response);
    },
    function(err){
        console.log(err);
    });

Websocket

Connect to one of our websocket endpoints and get real-time updates for the Bitcoin Global Price Index.

Ticker websocket

wsClient.connectToTickerWebsocket('global', 'BTCUSD', function(response) {
    console.log(response);
}, function(error){
    console.log(error)
}, function(){
    console.log("websocket closed");
});

Orderbook websocket

The orderbook channel starts by sending a "snapshot" message with the current state of the orderbook. Then it is followed by "update" messages that represent the changes in the orderbook.

If the amount for an order is 0, the order has been completed, so it needs to be removed from the orderbook.

If the amount is greater than 0 then we just update value.

var symbols = ['BTCUSD', 'ETHUSD'];
var exchange = 'bitfinex';
var ORDERBOOKS = {
    BTCUSD: {},
    ETHUSD: {}
};
var symbol = '';
wsClient.connectToOrderbookWebsocket(exchange, symbols, function(response){
    symbol = respnose.data.symbol;
    if(response.data.type === "snapshot"){
        ORDERBOOKS[symbol].asks = response.data.asks;
        ORDERBOOKS[symbol].bids = response.data.bids;
     }else{
       console.log(response.data.updates);
       for (var i = 0; i < response.data.updates.length; i++){
          var item = response.data.updates[i];
         if(item.amount === 0){
            delete(ORDERBOOKS[symbol][item.side][item.price]);
         }else{
           ORDERBOOKS[symbol][item.side][item.price] = item;
         }
       }
     }
}, function(err){
console.log(err);
});

Python PIP Package

pip install bitcoinaverage

Setup

from bitcoinaverage import RestfulClient
restful_client = RestfulClient("<secret key>", "<public key>")

Ticker data

ticker_global = restful_client.ticker_all_global(crypto="ETH", fiat="USD,EUR")
print(ticker_global)

Exchange data

all_bitstamp_data = restful_client.per_exchange_data('bitstamp')
all_coinbase_data = restful_client.per_exchange_data('gdax')

all_exchange_data_gbp_brl = restful_client.all_exchange_data(crypto='BTC', fiat='GBP,BRL')
You can’t perform that action at this time.
