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, jersey, us, tr, 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.com")
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:
        print(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)

binance_websocket_api_manager.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']

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 "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 Jersey, 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.je, 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 have to use the Binance Rest API (com, je, us, tr, jex, org) 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:

Exchange	Exchange string
Binance	`BinanceWebSocketApiManager(exchange="binance.com")`
Binance Testnet	`BinanceWebSocketApiManager(exchange="binance.com-testnet")`
Binance Margin	`BinanceWebSocketApiManager(exchange="binance.com-margin")`
Binance Margin Testnet	`BinanceWebSocketApiManager(exchange="binance.com-margin-testnet")`
Binance Isolated Margin	`BinanceWebSocketApiManager(exchange="binance.com-isolated_margin")`
Binance Isolated Margin Testnet	`BinanceWebSocketApiManager(exchange="binance.com-isolated_margin-testnet")`
Binance Futures	`BinanceWebSocketApiManager(exchange="binance.com-futures")`
Binance Futures Testnet	`BinanceWebSocketApiManager(exchange="binance.com-futures-testnet")`
Binance Jersey	`BinanceWebSocketApiManager(exchange="binance.je")`
Binance US	`BinanceWebSocketApiManager(exchange="binance.us")`
Binance TR	`BinanceWebSocketApiManager(exchange="trbinance.com")`
Binance JEX	`BinanceWebSocketApiManager(exchange="jex.com")`
Binance DEX	`BinanceWebSocketApiManager(exchange="binance.org")`
Binance DEX Testnet	`BinanceWebSocketApiManager(exchange="binance.org-testnet")`

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).
Supports subscribe/unsubscribe on all exchanges! (Take a look to the max supported subscriptions per stream in the endpoint configuration overview!)
UNICORN Binance WebSocket API respects Binance's API guidelines and protects you from avoidable reconnects and bans.
Support for multiple private !userData streams with different api_key and api_secret. (example_multiple_userdata_streams.py)
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_buffer which stores the receives in the RAM till you are able to process the data in the normal way again. Learn more!
Use separate stream_buffers for specific streams or users!
Watch the stream_signal_buffer to receive CONNECT, DISCONNECT and FIRST_RECEIVED_DATA signals 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 output parameter of create_stream() to control the output format.
Helpful management features like get_binance_api_status(), get_current_receiving_speed(), get_errors_from_endpoints(), get_limit_of_subscriptions_per_stream(), get_request_id(), get_result_by_request_id(), get_results_from_endpoints(), get_stream_buffer_length(), get_stream_info(), get_stream_list(), get_stream_id_by_label(), get_stream_statistic(), get_stream_subscriptions(), get_version(), is_update_availabe(), pop_stream_data_from_stream_buffer(), print_summary(), replace_stream(), set_stream_label(), set_ringbuffer_error_max_size(), subscribe_to_stream(), stop_stream(), stop_manager_with_all_streams(), unsubscribe_from_stream(), wait_till_stream_has_started() and many more! Explore them here.
Monitor the status of the created BinanceWebSocketApiManager() instance within your code with get_monitoring_status_plain() and specific streams with get_stream_info().
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 :)
Monitoring API service and a check_command for ICINGA/Nagios
Excessively tested on Linux, Mac and Windows

Donate

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, even small donations are very welcome.
