Npm node binance api

Binance

A wrapper for the Binance REST and WebSocket APIs. Uses promises and beautifies the binance API responses that normally use lots of one letter property names. For more information on the API and parameters for requests visit https://github.com/binance-exchange/binance-official-api-docs

Usage/Example

REST APIs

Example responses are only included for routes where the response is beautified, and therefore different than the official docs. Click on any function call to see the related route information in the official documentation.

ping([callback function])

For testing connectivity.

time([callback function])

Retrieves the current server time.

exchangeInfo([callback funcion])

Retrieves the current exchange trading rules and symbol information. Includes rate limits for request and orders, as well as restrictions placed on various values when ordering.

depth(query object|string, [callback function])

Retrieves the order book for a given symbol.

trades(query object|string, [callback function])

Retrieves the most recent trades for a given symbol(up to 500).

historicalTrades(query object|string, [callback function])

Retrieves historical trades by tradeId. If no tradeId is specified the most recent trades are returned.

aggTrades(query object|string, [callback function])

Get compressed, aggregate trades. Trades that fill at the same time, from the same order, with the same price will have the quantity aggregated.

klines(query object, [callback function])

Retrieve kline/candlestick bars for a symbol. Klines are uniquely identified by their open time.

ticker24hr(query object|string, [callback function])

Retrieve 24 hour price change statistics.

tickerPrice(query object|string, [callback function])

Retrieve latest price for a symbol or symbols.

bookTicker(query object|string, [callback function])

Retrieve best price/qty on the order book for a symbol or symbols.

newOrder(query object, [callback function])

Places a new order. Example:

testOrder(query object, [callback function])

Places a test order.

queryOrder(query object, [callback function])

Check an order’s status.

cancelOrder(query object, [callback function])

Cancel an open order.

openOrders(query object|string, [callback function])

Get all open orders for a symbol, or all symbols. Careful when accessing this with no symbol as the number of requests counted against the rate limiter is equal to the number of symbols currently trading on the exchange.

allOrders(query object|string, [callback function])

Retrieve all orders on an account, whether active, cancelled, or filled.

account([callback function])

Retrieve current account information including commision rates, trading permissions, and free/locked balances.

myTrades(query object|string, [callback function])

Retrieve all trades made by an account.

withdraw(query object|string, [callback function])

Make a withdrawal.

withdrawHistory(query object|string, [callback function])

Retrieve withdrawal history for an account for a specific asset, or all assets. Includes status.

depositHistory(query object|string, [callback function])

Retrieve deposit history for an account for a specific asset, or all assets. Includes status.

depositAddress(query object|string, [callback function])

Generate and retrieve a deposit address for a given asset.

accountStatus([callback function])

Retrieve account status.

startUserDataStream([callback function])

For use in conjunction with the user data websocket. Returns a listen key that must be specified. onUserData() will handle this for you when you pass it an instance of BinanceRest .

keepAliveUserDataStream(query object, [callback function])

The keep alive request needed to keep a user data websocket open. Will be automatically sent at a specified interval if using onUserData() .

closeUserDataStream(query object, [callback function])

Closes the user data stream.

allPrices([callback function])

Returns the latest price for all symbols. This route appears on the old API document, but does not appear in the most recent set of docs. You should probably use tickerPrice() instead as it utilizes a route with a newer version.

allBookTickers([callback function])

Returns the best price/qty on the order book for all symbols. This route appears on an old API document, but does not appear in the most recent set of docs. You should probably use bookTicker() instead as it utilizes a route with a newer version.

WebSocket APIs

onDepthUpdate(symbol, eventHandler)

Order book price and quantity depth updates used to locally manage an order book, pushed every second. Function call returns the websocket, an instance of https://www.npmjs.com/package/ws

Stream Name: @depth

onDepthLevelUpdate(symbol, eventHandler)

Top bids and asks, pushed every second. Valid are 5, 10, or 20. Function call returns the websocket, an instance of https://www.npmjs.com/package/ws. See official docs for response.

Stream Name: @depth

onKline(symbol, interval, eventHandler)

Pushes updates to the current klines/candlesticks every second. Valid intervals are described here. Returns the websocket, an instance of https://www.npmjs.com/package/ws

Stream Name: @kline_

onAggTrade(symbol, eventHandler)

Pushes trade information that is aggregated for a single taker order. Returns the websocket, an instance of https://www.npmjs.com/package/ws

Stream Name: @aggTrade

onTrade(symbol, eventHandler)

Pushes raw trade information, with each trade having a unique buyer and seller. Returns the websocket, an instance of https://www.npmjs.com/package/ws

Stream Name: @trade

onTicker(symbol, eventHandler)

24 hour ticker stats for a single symbol pushed every second. Returns the websocket, an instance of https://www.npmjs.com/package/ws

Stream Name: @ticker

onAllTickers(eventHandler)

24hr Ticker statistics for all symbols in an array, pushed every second. Returns the websocket, an instance of https://www.npmjs.com/package/ws

Stream Name: !ticker@arr

onCombinedStream(streams, eventHandler)

streams should be an array of stream names. You may specify these explicitly, or you can use some helper functions to generate them:

onUserData(binanceRest, eventHandler, [interval])

Will return the websocket via promise, interval defaults to 60000(ms), and is the amount of time between calls made to keep the user stream alive. binanceRest should be an instance of BinanceRest that will be used to get the listenKey and keep the stream alive.

Processing

Filters

Quantities and prices used when creating orders must fall within the guidelines provided by the filters in symbolInfo responses. The code below shows how to turn a quantity and price into acceptable values for creating an order. The results vary depending on the symbol used, since different symbols have different filters.

Symbol information can be obtained from exchangeInfo([callback funcion])

Timestamp errors

Most can be resolved by adjusting your recvWindow a bit larger, but if your clock is constantly or intermittently going out of sync with the server, the library is capable of calculating the drift and adjusting the timestamps. You have some options. The first is to add the handleDrift option to the constructor, setting it to true .

In this case, if your clock is ahead of the server’s, or falls behind and is outside the recvWindow , and a request fails, the library will calculate the drift of your clock and reattempt the request. It will also use the drift value to adjust all subsequent calls. This may add more time to the initial requests that fail, and could potentially affect highly time sensitive trades.

The alternative is to use the startTimeSync(interval_in_ms) and endTimeSync functions. The former will begin an interval, and each time it’s called the drift will be calculated and used on all subsequent requests. The default interval is 5 minutes, and it should be specified in milliseconds. The latter will clear the interval. You may also calculate the drift manually by calling calculateDrift() . The resulting value will be stored internally and used on all subsequent calls.

binance-api-node

A complete API wrapper for the Binance API.

Note: This wrapper uses Promises, if they are not supported in your environment, you might want to add a polyfill for them.

For PRs or issues, head over to the source repository.

Installation

Getting started

Import the module and create a new client. Passing api keys is optional only if you don’t plan on doing authenticated calls. You can create an api key here.

If you do not have an appropriate babel config, you will need to use the basic commonjs requires.

Every REST method returns a Promise, making this library async await ready. Following examples will use the await form, which requires some configuration you will have to lookup.
