Supported Currencies
Our APIs support 5 sets of symbols. When requesting any price related endpoint you will need to specify which set of symbols your required symbols resides in.
The Symbols (currency pairs), are a core concept of our platform, understanding how each symbols is derived is crucial for efficient usage of our APIs, please take the time to ensure you are aware of where and why they reside. If further clarification is needed please do Email Us and we will be more than happy to assist, or join us on Slack!
Below you can find descriptions for each symbol_set.
| Symbol_Set | Description | Example |
|---|---|---|
| Global | This set provides global symbols that are derived from the Local currency markets. Symbols supported in this set will comprise a Cryptocurrency against approximately 170 fiat currencies. | BTCUSD,BTCMKD,ETHAUD |
| Local | This set includes Cryptocurrencies that are actively traded to a fiat currency on an exchange. These are also known as our Currency Markets. | BTCUSD,ETHEUR,LTCUSD |
| Crypto | This set comprises Crypto/Crypto pairs only. | XMRBTC,ETHXRP,LTCETH |
| Tokens | This set includes any Token that is not in itself a coin or crypto, and instead resides on top of another blockchain such as Ethereum. These symbols can either be Token/Crypto or Token/Fiat | OMGUSD,REPBTC,EOSBTC |
| Light | This set includes Tokens and Cryptocurrencies that are more obscure but show potential. The responses from this symbol set are shorter but still provide all essential market data. |
Price Symbols (Ticker)
Returns a list of symbol sets and supported symbols for ticker endpoints.
Calculating reverse symbols
If you wish to get price data for say Bitcoin to Ethereum, symbol BTCETH, but only ETHBTC is supported in our API, you can easily derive the BTCETH price data from our ETHBTC price data.
- For all prices: Calculate 1/price. For example if the last value for ETHBTC is 0.0406, then BTCETH = 1 / 0.0406 = 24.63
- For volume: Multiply the given volume by the given last price. With the ETHBTC example, if the volume in ETH is 527348 and the last price is 0.0406 then the volume in BTC will be 527348 * 0.0406 = 21410.328

Historical Data
Improvement to the History Data API
Previously our history API automatically returned minute data when your request timestamp was within 24h period, afterwards it automatically moved to hour data from 1 day to 30 days and then provided day data when the timestamp exceeded 30 days in the past.
This resulted in different api responses when the same timestamp was requested just two days apart.
We have improved this by adding a resolution parameter that lets you specify what type of dataset you would like to access: minute, hour or day.
Api call credits
This endpoint can return well over 100 data points and can spend more than one API call credit. One credit call is used for 100 data points, rounded up.
If one response contains between 101 and 200 data points you will spend 2 call credits. If it contains between 201 and 300 data points you will spend 3 call credits etc.
History limits by plan
The history API endpoints will return different data size depending on your plan.
| Plan | Minute | Hour | Day |
|---|---|---|---|
| Developer | 2 hours | 10 days | 3 months |
| Startup | 24 hours | 31 days | 1 year |
| Grow | 24 hours | 31 days | 7 years |
| Dominate | 24 hours | 31 days | 7 years |
These limits are enforced for all history endpoints:
- History data by period
- History data
sincetimestamp - History data
attimestamp

Websocket API
Deprecated
Overview
The websocket feed provides real-time market data for price indices and exchanges.
Root URL: wss://apiv2.Index-Bitcoin.com/
Authentication
The procedure for authenticating websocket connections is the following:
Step 1.
- Send a GET request, signed with your public_key and secret_key to
https://apiv2.Index-Bitcoin.com/websocket/get_ticket - You will receive the ticker in the response. e.g:
{"ticket": "ASDFXZCVASDF2341234"} - The method to sign the above request is explained in the general Authentication Section
Step 2.
Connect to the endpoints using their respective urls including public_key and ticket parameters. An example for subscribing to the single ticker endpoint would be:
wss://apiv2.Index-Bitcoin.com/websocket/ticker?ticket=<THE RECEIVED TICKET>&public_key=<YOUR PUBLIC KEY>
Notes.
- If either of the parameters, public_key or ticket, are wrong, then the connection will be closed immediately by our server.
- The ticket can only be used once.
Channels
After authentication is complete the websocket connection is established, you may then subscribe to the required channel.
Available channels are listed below, they are single ticker, multiple ticker, single exchange and multiple exchanges.

Websocket API V2
Deprecated
Overview
Version 2 of our Websocket API that pushes realtime updates as soon as they happen instead on a set interval of seconds, depending on your plan.
This allows for faster updates with less bandwidth because we push updates of only the prices that have changed.
Root URL: wss://apiv2.Index-Bitcoin.com/websocket/v2
Client Limits
Our Websocket API V2 is available to Grow and Dominate plans and our legacy Enterprise clients.
Data Frequency
Updates are pushed in real time, so they depend on the activity of the markets. For activelly traded cryptocurrencies like Bitcoin and Ethereum this could be less than a second, but for more obscure cryptocurrencies it could be minutes appart.
Authentication
The procedure for authenticating these websocket connections is the same as in version 1 except the urls are changed.
Step 1.
- Send a GET request, signed with your public_key and secret_key to
https://apiv2.Index-Bitcoin.com/websocket/v2/get_ticket - You will receive the ticker in the response. e.g:
{"ticket": "ASDFXZCVASDF2341234"} - The method to sign the above request (for getting ticket) is explained in the general Authentication Section
Step 2.
Connect to the channels using their respective urls including public_key and ticket parameters. An example for subscribing to the ticker channel would be:
wss://apiv2.Index-Bitcoin.com/websocket/v2/ticker?ticket=<THE RECEIVED TICKET>&public_key=<YOUR PUBLIC KEY>
Notes.
- If either of the parameters, public_key or ticket, are wrong, then the connection will be closed immediately by our server.
- The ticket can only be used once.
Channels
After authentication is complete the websocket connection is established, you may then send your subscription message to the channel.
There are two channels, ticker and exchanges, that can be used to connect to one or more indices or exchanges respectively.
Ticker
URL
wss://apiv2.Index-Bitcoin.com/websocket/v2/ticker
This channel returns ticker data for multiple symbols grouped in symbol sets. The symbols sets are local, global, crypto and tokens. Every time you send a new subscription message, the new symbols are added to the response in their symbol set. The unsubscribe message does not close the connect but removes symbols from the response.
Example Subscribe Message
{
"event": "message",
"data": {
"operation": "subscribe",
"options": {
"currency_list": ["BTCUSD", "BTCGBP", "ETHUSD"],
"symbol_set": "global"
}
}
}
Example Unsubscribe Message

Websocket API V3
Overview
Websocket API version 3 that focuses on offering higher availability and uptime than version 2.
Our Websocket API pushes realtime updates as soon as they happen instead on a set interval of seconds.
This allows for faster updates with less bandwidth because we push updates of only the prices that have changed.
Root URL: wss://apiv2.Index-Bitcoin.com/websocket/v3
Client Limits
Our Websocket API V3 is available to Grow and Dominate plans.
| Plan | Connections limit | Ticker symbols | Exchanges symbols |
|---|---|---|---|
| Grow | 10 | 100 | 200 |
| Dominate | 20 | 300 | 500 |
Data Frequency
Updates are pushed in real time, so they depend on the activity of the markets. For actively traded cryptocurrencies like Bitcoin and Ethereum this could be less than a second, but for more obscure cryptocurrencies it could be minutes apart.
Authentication
Step 1.
- Send a GET request, with your public key in the header
x-ba-key, tohttps://apiv2.Index-Bitcoin.com/websocket/v3/get_ticket - You will receive the ticker in the response. e.g:
{"ticket": "ASDFXZCVASDF2341234"}

Notes.
- If either of the parameters, public_key or ticket, are wrong, then the connection will be closed immediately by our server.
- The ticket can be used once. You need to generate new ticket for every connection.
Channels
After the websocket connection is established you may send your subscription message to specify the channel and the subscription options.
There are 4 channels: ticker, exchanges, orderbooks and tradebooks.
Ticker
This channel returns ticker data for multiple symbols grouped in symbol sets.
The symbols sets are local, global, crypto and tokens.
You can check which cryptocurrency markets belong in which symbol set here: https://apiv2.Index-Bitcoin.com/constants/indices/ticker/symbols/
Every time you send a new subscription message, the new symbols are added to the response in their symbol set.
The unsubscribe message does not close the connection but removes symbols from the response.
Example Subscribe Message
{
"event": "message",
"data": {
"channel": "multiple-ticker",
"operation": "subscribe",
"options": {
"currency_list": ["BTCUSD", "BTCGBP", "ETHUSD"],
"symbol_set": "global"
}
}
}
Example Unsubscribe Message
{
"event": "message",
"data": {
"channel": "multiple-ticker",
"operation": "unsubscribe",
"options": {
"currency_list": ["BTCUSD"],
"symbol_set": "global"
}
}
}
Example Response
{
"event": "message",
"data":{
"local": {
"BTCUSD": {...data},
"ETHEUR": {...data},
...
},
"global":{
"BTCGBP": {...data},
"BCHCAD": {...data},
...
}
}
}
Exchanges Price Data
This channel returns data for multiple exchanges symbols. Every time you send a new subscription message, the requested exchanges symbols are added to the response.
The unsubscribe message does not close the websocket connection but only removes the unsubscribed symbols from the response.
Example Subscribe Message
{
"event": "message",
"data": {
"channel": "multiple-exchanges",
"operation": "subscribe",
"options": {
"exchange": ["coinbasepro"],
"currency_list": ["BTCUSD", "ETHUSD", "BCHUSD"]
}
}
}
Example Unsubscribe Message
{
"event": "message",
"data": {
"channel": "multiple-exchanges",
"operation": "unsubscribe",
"options": {
"exchange": ["bitstamp"],
"currency_list": ["BTCUSD"]
}
}
}
Example Response
{
“event": "message",
“data": {
"bitstamp": {
"BTCUSD": {...data},
"ETHUSD": {...data},
},
"coinbasepro": {
"LTCUSD": {...data},
},
...
}
}
Exchanges Orderbook Data
This channel returns orderbook data for one or more symbols from a single exchange.
Example Subscribe Message
{
"event": "message",
"data": {
"channel": "orderbooks",
"operation": "subscribe",
"symbols": ["BTCUSD", "BTCEUR"],
"exchange": "coinbasepro"
}
}
Example Unsubscribe Message
{
"event": "message",
"data": {
"operation": "unsubscribe",
"symbols": ["ETHBTC", "LTCBTC"],
"exchange": "binance",
}
}
The first response this channel provides is a snapshot of the current state of the orderbook.
Snapshot Response
{
“event": "message",
“data": {
bids: [sorted array of buy orders (sorted descending)],
asks: [sorted array of sell orders (sorted ascending)],
symbol: "BTCUSD",
type: "snapshot"
}
}
Order format
{
price: 8100,
amount: 1.9384
}
After the snapshot is sent, the channel will continue sending update events that represent the changes in the orderbook.
Update Response
{
symbol: "BTCUSD",
updates: [array of updated orders],
type: "update
}
Update order format
{
side: "bids",
price: 8100,
amount: 1,
}
Every updated order in the updates field has the following format. The side value can be bids or asks representing the array where this order is located. The amount is greater or equal to 0. If it is 0, then the order has been completed and is no longer part of the orderbook. If it is greater than 0 then this is the new amount for the given price and needs to be updated in the orderbook.
Keeping an up-to-date orderbook
Keeping an up-to-date orderbook
const ba = require('Index-Bitcoin');
var publicKey = 'yourPublicKey';
var secretKey = 'yourSecretKey';
var wsClient = ba.websocketClient(publicKey, secretKey);
var symbols = ['BTCUSD', 'ETHUSD'];
var exchange = 'bitfinex';
var ORDERBOOKS = {
BTCUSD: {},
ETHUSD: {}
};
var symbol = '';
var i, item;
wsClient.connectToOrderbookWebsocket(exchange, symbols, function(response){
symbol = respnose.data.symbol;
if(response.data.type === "snapshot"){
for (var i = 0; i < response.data.asks.length; i++){
item = response.data.asks[i];
ORDERBOOKS[symbol].asks[item.price] = item;
}
for (var j = 0; j < response.data.bids.length; j++){
item = response.data.bids[i];
ORDERBOOKS[symbol].bids[item.price] = item;
}
}else{
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);
});
The process of keeping an orderbook is quite straightforward:
- Connect to the orderbook channel (our npm package makes this easier).
- If the response is of type snapshot then store the arrays of bids(buy orders) and asks(sell orders).
- Otherwise the respnose is of type update. Iterate the update array from the response and update the orderbook.
- If the amount is 0 then remove that price level from the orderbook.
- If the amount is greater than 0 then update the price level.
In this example we're using our npm package that can be installed with:
npm install Index-Bitcoin
