This is a lightweight library that works as a connector to Binance public API

• Supported APIs:
  • /api/*
  • /sapi/*
  • Spot Websocket Market Stream
  • Spot User Data Stream
• Inclusion of test cases and examples
• Customizable base URL, request timeout and HTTP proxy
• Response metadata can be displayed

pip install binance-connector

https://binance-connector.readthedocs.io

Usage examples:

from binance.spot import Spot

client = Spot()

# Get server timestamp
print(client.time())
# Get klines of BTCUSDT at 1m interval
print(client.klines("BTCUSDT", "1m"))
# Get last 10 klines of BNBUSDT at 1h interval
print(client.klines("BNBUSDT", "1h", limit=10))

# API key/secret are required for user data endpoints
client = Spot(api_key='<api_key>', api_secret='<api_secret>')

# Get account and balance information
print(client.account())

# Post a new order
params = {
    'symbol': 'BTCUSDT',
    'side': 'SELL',
    'type': 'LIMIT',
    'timeInForce': 'GTC',
    'quantity': 0.002,
    'price': 9500
}

response = client.new_order(**params)
print(response)

Please find examples folder to check for more endpoints.

Binance supports HMAC and RSA API authentication.

# HMAC: pass API key and secret
client = Client(api_key, api_secret)
print(client.account())

# RSA Keys
client = Client(api_key=api_key, private_key=private_key)
print(client.account())

# Encrypted RSA Key
client = Client(api_key=api_key, private_key=private_key, private_key_pass='password')
print(client.account())

Please find examples/spot/trade/get_account.py for more details.

Spot Testnet is available, it can be used to test /api/* endpoints.

• /sapi/* endpoints are not available.
• No UI.
• Steps to setup testnet API key. https://dev.binance.vision/t/99

To use testnet:

from binance.spot import Spot as Client

client = Client(base_url='https://testnet.binance.vision')
print(client.time())

If base_url is not provided, it defaults to api.binance.com.
It's recommended to pass in the base_url parameter, even in production as Binance provides alternative URLs in case of performance issues:

• https://api1.binance.com
• https://api2.binance.com
• https://api3.binance.com

PEP8 suggests lowercase with words separated by underscores, but for this connector, the methods' optional parameters should follow their exact naming as in the API documentation.

# Recognised parameter name
response = client.cancel_oco_order('BTCUSDT', orderListId=1)

# Unrecognised parameter name
response = client.cancel_oco_order('BTCUSDT', order_list_id=1)

Additional parameter recvWindow is available for endpoints requiring signature.
It defaults to 5000 (milliseconds) and can be any value lower than 60000(milliseconds). Anything beyond the limit will result in an error response from Binance server.

from binance.spot import Spot as Client

client = Client(api_key, api_secret)
response = client.get_order('BTCUSDT', orderId=11, recvWindow=10000)

timeout is available to be assigned with the number of seconds you find most appropriate to wait for a server response.
Please remember the value as it won't be shown in error message no bytes have been received on the underlying socket for timeout seconds.
By default, timeout is None. Hence, requests do not time out.

from binance.spot import Spot as Client

client= Client(timeout=1)

Proxy is supported.

from binance.spot import Spot as Client

proxies = { 'https': 'http://1.2.3.4:8080' }

client= Client(proxies=proxies)

The Binance API server provides weight usages in the headers of each response. You can display them by initializing the client with show_limit_usage=True:

from binance.spot import Spot as Client

client = Client(show_limit_usage=True)
print(client.time())

returns:

{'data': {'serverTime': 1587990847650}, 'limit_usage': {'x-mbx-used-weight': '31', 'x-mbx-used-weight-1m': '31'}}

You can also display full response metadata to help in debugging:

client = Client(show_header=True)
print(client.time())

returns:

{'data': {'serverTime': 1587990847650}, 'header': {'Context-Type': 'application/json;charset=utf-8', ...}}

If ClientError is received, it'll display full response meta information.

Setting the log level to DEBUG will log the request URL, payload and response text.

There are 2 types of error returned from the library:

• binance.error.ClientError
  • This is thrown when server returns 4XX, it's an issue from client side.
  • It has 4 properties:
    • status_code - HTTP status code
    • error_code - Server's error code, e.g. -1102
    • error_message - Server's error message, e.g. Unknown order sent.
    • header - Full response header.
• binance.error.ServerError
  • This is thrown when server returns 5XX, it's an issue from server side.

from binance.websocket.spot.websocket_client import SpotWebsocketClient as WebsocketClient

def message_handler(message):
    print(message)

ws_client = WebsocketClient()
ws_client.start()

ws_client.mini_ticker(
    symbol='bnbusdt',
    id=1,
    callback=message_handler,
)

# Combine selected streams
ws_client.instant_subscribe(
    stream=['bnbusdt@bookTicker', 'ethusdt@bookTicker'],
    callback=message_handler,
)

ws_client.stop()

More websocket examples are available in the examples folder

Once connected, the websocket server sends a ping frame every 3 minutes and requires a response pong frame back within a 10 minutes period. This package handles the pong responses automatically.

from binance.websocket.spot.websocket_client import SpotWebsocketClient as WebsocketClient

ws_client = WebsocketClient(stream_url='wss://testnet.binance.vision')

# In case packages are not installed yet
pip install -r requirements/requirements-test.txt

pytest

Futures and Vanilla Options APIs are not supported:
