Description | Live Demo | Installation | How To | Documentation | Change Log | Wiki | Social | Notifications | Bugs | Contributing

A python API to use the Binance Websocket API's (com, com-margin, com-futures, jersey, us, jex, dex/chain+testnet) in a easy, fast, flexible, robust and fully-featured way.

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

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

And 4 more lines to print the receives:

while True:
    oldest_stream_data_from_stream_buffer = binance_websocket_api_manager.pop_stream_data_from_stream_buffer()
    if oldest_stream_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_stream_data_from_stream_buffer)

Subscribe / unsubscribe new markets and channels:

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

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

binance_websocket_api_manager.unsubscribe_from_stream(stream_id, markets=markets)

binance_websocket_api_manager.unsubscribe_from_stream(stream_id, channels=channels)

Discover even more possibilities or use this script to stream everything from "".

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


The python module UNICORN Binance WebSocket API provides an API to the Binance Websocket API`s of Binance, Binance Margin, Binance Futures, Binance Jersey, Binance US, Binance JEX, Binance DEX and Binance DEX Testnet and supports the streaming of all public streams like trade, kline, ticker, depth, bookTicker, forceOrder 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,, or - for the DEX you need a user address from or and you can get funds for the testnet.

The module requires python 3.6.1 or above, as it depends on pythons latest asyncio features for asynchronous/concurrent processing. The current dependencies are listed here.

Be aware that the Binance websocket API just offers to receive data. If you would like to set orders, withdraws and so on, you have to use the Binance Rest API (com, je, us, jex, org) in combination.

What are the benefits of the UNICORN Binance WebSocket API?

  • Fully managed websockets and 100% auto-reconnect!
  • Supported exchanges:
    • Binance BinanceWebSocketApiManager(exchange="")
    • Binance Margin BinanceWebSocketApiManager(exchange="")
    • Binance Futures BinanceWebSocketApiManager(exchange="")
    • Binance Jersey BinanceWebSocketApiManager(exchange="")
    • Binance US BinanceWebSocketApiManager(exchange="")
    • Binance JEX BinanceWebSocketApiManager(exchange="")
    • Binance DEX BinanceWebSocketApiManager(exchange="")
    • Binance DEX testnet BinanceWebSocketApiManager(exchange="")
  • Streams are processing asynchronous/concurrent (python asyncio) and each stream is started in a separate thread, but you dont need to deal with asyncio in your code!
  • No use of the twisted module, so you can use this lib in a daemonized application (compatible with python-daemon).
  • Supports subscriptions/unsubscribe on all exchanges! (Maximum 1024 subscriptions per stream!)
  • UNICORN Binance WebSocket API respects Binance's API guidelines and protects you from reconnects and a ban.
  • Support for multiple private !userData streams with different api_key and api_secret. (
  • If you can not store your data in cause of a temporary technical issue, you can kick back the data to the stream_buffer which stores the receives in the RAM till you are able to process the data in the normal way again. Learn more!
  • Compatible with UnicornFy to convert received raw data from crypto API endpoints into well-formed python dictionaries.
  • Helpful management features like get_binance_api_status(), get_stream_info(), get_stream_list(), get_stream_statistic(), get_stream_subscriptions(), replace_stream(), wait_till_stream_has_started(), get_current_receiving_speed(), subscribe_to_stream(), unsubscribe_from_stream() and many more, explore them here.
  • Nice to use with iPython: "IPython (Interactive Python) is a command shell for interactive computing that offers introspection, rich media, shell syntax, tab completion, and history." ( iPython
  • Monitoring API service and a check_command for ICINGA/Nagios icinga2-demo
  • Excessively tested on Linux, Mac and Windows

We love open source!


Since you are probably a developer yourself, you will understand very well that the creation of open source software is not free - it requires technical knowledge, a lot of time and also financial expenditure.

If you would like to help me to dedicate my time and energy to this project, donations are very welcome.
