UNICORN Binance WebSocket API

Description | Live Demo | Installation | How To | Documentation | Examples | Change Log | Wiki | Social | Notifications | Bugs | Contributing | Commercial Support | Donate

An unofficial Python API to use the Binance Websocket API`s (com+testnet, com-margin+testnet, com-isolated_margin+testnet, com-futures+testnet, us, tr, jex, dex/chain+testnet) in a easy, fast, flexible, robust and fully-featured way.

Part of ‘UNICORN Binance Suite’.

Create a multiplex websocket connection to Binance with just 3 lines of code:

from unicorn_binance_websocket_api.unicorn_binance_websocket_api_manager import BinanceWebSocketApiManager

ubwa = BinanceWebSocketApiManager(exchange="binance.com")
ubwa.create_stream(['trade', 'kline_1m'], ['btcusdt', 'bnbbtc', 'ethbtc'])

And 4 more lines to print the receives:

while True:
    oldest_data_from_stream_buffer = ubwa.pop_stream_data_from_stream_buffer()
    if oldest_data_from_stream_buffer:
        print(oldest_data_from_stream_buffer)

Basically that’s it, but there are more options:

Convert received raw webstream data into well-formed Python dictionaries with UnicornFy:

unicorn_fied_stream_data = UnicornFy.binance_com_websocket(oldest_data_from_stream_buffer)

or

ubwa.create_stream(['trade'], ['btcusdt'], output="UnicornFy")

Subscribe / unsubscribe new markets and channels:

markets = ['engbtc', 'zileth']
channels = ['kline_5m', 'kline_15m', 'kline_30m', 'kline_1h', 'kline_12h', 'depth5']

ubwa.subscribe_to_stream(stream_id, channels=channels, markets=markets)

ubwa.unsubscribe_from_stream(stream_id, markets=markets)

ubwa.unsubscribe_from_stream(stream_id, channels=channels)

Discover even more possibilities or use this script to stream everything from “binance.com”.

This should be known by everyone using this lib: Do you want consistent data from binance?

Description

The Python module UNICORN Binance WebSocket API provides an API to the Binance Websocket API`s of Binance (+Testnet), Binance Margin (+Testnet), Binance Isolated Margin (+Testnet), Binance Futures (+Testnet), Binance US, Binance TR, Binance JEX, Binance DEX and Binance DEX Testnet and supports the streaming of all public streams like trade, kline, ticker, depth, bookTicker, forceOrder, compositeIndex and blockheight and also all private userData streams which needs to be used with a valid api_key and api_secret from the Binance Exchange www.binance.com, testnet.binance.vision, www.binance.us or www.jex.com - for the DEX you need a user address from www.binance.org or testnet.binance.org and you can get funds for the testnet.

Be aware that the Binance websocket API just offers to receive data. If you would like to set orders, withdraws and so on, you can to use the UNICORN Binance REST API in combination.
