UNICORN Binance WebSocket API

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:

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)


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?


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.

What are the benefits of the UNICORN Binance WebSocket API?

  • Fully managed websockets and 100% auto-reconnect! Also handles maintenance windows!
  • Supported exchanges:

Installation and Upgrade

The module requires Python 3.7 or above, as it depends on Pythons latest asyncio features for asynchronous/concurrent processing.

The current dependencies are listed here.

If you run into errors during the installation take a look here.

A wheel of the latest release with PIP from PyPI

pip install unicorn-binance-websocket-api --upgrade

From source of the latest release with PIP from Github

Linux, macOS, ...

Run in bash:

pip install https://github.com/oliver-zehentleitner/unicorn-binance-websocket-api/archive/$(curl -s https://api.github.com/repos/oliver-zehentleitner/unicorn-binance-websocket-api/releases/latest | grep -oP '"tag_name": "\K(.*)(?=")').tar.gz --upgrade


Use the below command with the version (such as 1.27.0) you determined here:

pip install https://github.com/oliver-zehentleitner/unicorn-binance-websocket-api/archive/1.27.0.tar.gz --upgrade

From the latest source (dev-stage) with PIP from Github

This is not a release version and can not be considered to be stable!

We love open source!

Commercial Support

Need a Python developer or consulting?

Contact me for a non-binding and free consultation via my company LUCIT from Vienna (Austria) or via Telegram.

Developing, documenting and testing the UNICORN Binance Suite and supporting the community takes a lot of time and time is a form of cost. I am extremely happy to do this, but need a solution for sharing the costs.

I think we are lucky, as our community consists of traders and programmers I expect to find mostly rational thinking people who also benefit financially from these libraries.

I would like to create a fair model for funding. My goals are that unicorn-binance-websocket-api, unicorn-binance-rest-api and unicorn-fy remain freely available as open source and that I am compensated at least to some extent and thus can invest my time more easily.

If you know the hooker principle from negotiation research or game theory, you know about the problem that people don't often pay for something out of their own impulse if they have already received it for free.

So my idea is to give every donor who gives an amount over 50 EUR access to a private Github repository where Python classes for trading algos are provided (OrderBook, advanced stop-loss, ...). Moreover, maybe a nice ApiTrader community will be formed.

So the donor not only helps to push the open source development but also gets access to a well maintained collection of practical code for little money.

Furthermore community members can help me by donating own developments to make the unicorn-coding-club repository more attractive to create further incentives for new donors. This way we generate added value for all sides in an uncomplicated way.

If you donated at least 50 EUR (without transaction fee), please send me a message with a confirmation and your Github username via https://www.lucit-development.co/contact.html, I will invite you to the unicorn-coding-club as soon as possible.
