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: print(oldest_data_from_stream_buffer)
Basically that’s it, but there are more options:
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)
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!

Streams are processing asynchronous/concurrent (Python asyncio) and each stream is started in a separate thread, so 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).
UNICORN Binance WebSocket API respects Binance’s API guidelines and protects you from avoidable reconnects and bans.
Support for multiple private
!userDatastreams with different
Pick up the received data from the
stream_buffer- if you can not store your data in cause of a temporary technical issue, you can kick back the data to the
stream_bufferwhich stores the receives in the RAM till you are able to process the data in the normal way again. Learn more!
FIRST_RECEIVED_DATAsignals about the streams! Learn more!
Get the received data unchanged as received, as Python dictionary or converted with UnicornFy into well-formed Python dictionaries. Use the
create_stream()to control the output format.
Helpful management features like
wait_till_stream_has_started()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.” (example_interactive_mode.py)
Also nice to use with the Jupyter Notebook :)
Excessively tested on Linux, Mac and Windows

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.
pip install unicorn-binance-websocket-api --upgrade
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
This is not a release version and can not be considered to be stable!
pip install https://github.com/oliver-zehentleitner/unicorn-binance-websocket-api/tarball/master --upgrade

We open source!
Need a Python developer or consulting?
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.
