# Binance Futures Public API Connector Python
[](https://www.python.org/downloads/)
[](https://opensource.org/licenses/MIT)
This is a lightweight library that works as a connector to [Binance Futures public API](https://binance-docs.github.io/apidocs/futures/en/)
- Supported APIs:
- USDT-M Futures `/fapi/*`
- COIN-M Delivery `/dapi/*`
- Futures/Delivery Websocket Market Stream
- Futures/Delivery User Data Stream
- Inclusion of examples
- Customizable base URL, request timeout
- Response metadata can be displayed
## Installation
```bash
pip install binance-futures-connector
```
## RESTful APIs
Usage examples:
```python
from binance.cm_futures import CMFutures
cm_futures_client = CMFutures()
# get server time
print(cm_futures_client.time())
cm_futures_client = CMFutures(key='<api_key>', secret='<api_secret>')
# Get account information
print(cm_futures_client.account())
# Post a new order
params = {
'symbol': 'BTCUSDT',
'side': 'SELL',
'type': 'LIMIT',
'timeInForce': 'GTC',
'quantity': 0.002,
'price': 59808
}
response = cm_futures_client.new_order(**params)
print(response)
```
Please find `examples` folder to check for more endpoints.
## Authentication
Binance supports HMAC and RSA API authentication.
```python
# HMAC Authentication
client = Client(api_key, api_secret)
print(client.account())
# RSA Authentication
key = ""
with open("/Users/john/private_key.pem", "r") as f: # Location of private key file
private_key = f.read()
private_key_passphrase = "" # Optional: only used for encrypted RSA key
client = Client(key=key, private_key=private_key, private_key_passphrase=private_key_passphrase)
print(client.account())
```
Please see `examples/um_futures/trade/get_account.py` or `examples/cm_futures/trade/get_account.py` for more details.
### Base URL
For USDT-M Futures, if `base_url` is not provided, it defaults to `fapi.binance.com`.<br/>
For COIN-M Delivery, if `base_url` is not provided, it defaults to `dapi.binance.com`.<br/>
It's recommended to pass in the `base_url` parameter, even in production as Binance provides alternative URLs
### Optional parameters
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.
```python
# Recognised parameter name
response = client.query_order('BTCUSDT', orderListId=1)
# Unrecognised parameter name
response = client.query_order('BTCUSDT', order_list_id=1)
```
### RecvWindow parameter
Additional parameter `recvWindow` is available for endpoints requiring signature.<br/>
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.
```python
from binance.cm_futures import CMFutures
cm_futures_client = CMFutures(key='<api_key>', secret='<api_secret>')
response = cm_futures_client.query_order('BTCUSDT', orderId=11, recvWindow=10000)
```
### Timeout
`timeout` is available to be assigned with the number of seconds you find most appropriate to wait for a server response.<br/>
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_.<br/>
By default, `timeout` is None. Hence, requests do not time out.
```python
from binance.cm_futures import CMFutures
client= CMFutures(timeout=1)
```
### Proxy
proxy is supported
```python
from binance.cm_futures import CMFutures
proxies = { 'https': 'http://1.2.3.4:8080' }
client= CMFutures(proxies=proxies)
```
### Response Metadata
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`:
```python
from binance.cm_futures import CMFutures
client = CMFutures(show_limit_usage=True)
print(client.time())
```
returns:
```python
{'limit_usage': {'x-mbx-used-weight-1m': '1'}, 'data': {'serverTime': 1653563092778}}
```
You can also display full response metadata to help in debugging:
```python
client = Client(show_header=True)
print(client.time())
```
returns:
```python
{'data': {'serverTime': 1587990847650}, 'header': {'Context-Type': 'application/json;charset=utf-8', ...}}
```
If `ClientError` is received, it'll display full response meta information.
### Display logs
Setting the log level to `DEBUG` will log the request URL, payload and response text.
### Error
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.
## Websocket
### Connector v4
WebSocket can be established through the following connections:
- USD-M WebSocket Stream (`https://binance-docs.github.io/apidocs/futures/en/#websocket-market-streams`)
- COIN-M WebSocket Stream (`https://binance-docs.github.io/apidocs/delivery/en/#websocket-market-streams`)
```python
# WebSocket Stream Client
import time
from binance.websocket.um_futures.websocket_client import UMFuturesWebsocketClient
def message_handler(_, message):
logging.info(message)
my_client = UMFuturesWebsocketClient(on_message=message_handler)
# Subscribe to a single symbol stream
my_client.agg_trade(symbol="bnbusdt")
time.sleep(5)
logging.info("closing ws connection")
my_client.stop()
```
#### Request Id
Client can assign a request id to each request. The request id will be returned in the response message. Not mandatory in the library, it generates a uuid format string if not provided.
```python
# id provided by client
my_client.agg_trade(symbol="bnbusdt", id="my_request_id")
# library will generate a random uuid string
my_client.agg_trade(symbol="bnbusdt")
```
#### Proxy
Proxy is supported for both WebSocket CM futures and UM futures.
To use it, pass in the `proxies` parameter when initializing the client.
The format of the `proxies` parameter is the same as the one used in the Spot RESTful API.
It consists on a dictionary with the following format, where the key is the type of the proxy and the value is the proxy URL:
For websockets, the proxy type is `http`.
```python
proxies = { 'http': 'http://1.2.3.4:8080' }
```
You can also use authentication for the proxy by adding the `username` and `password` parameters to the proxy URL:
```python
proxies = { 'http': 'http://username:password@host:port' }
```
```python
# WebSocket Stream Client
import time
from binance.websocket.um_futures.websocket_client import UMFuturesWebsocketClient
proxies = {'http': 'http://1.2.3.4:8080'}
def message_handler(_, message):
logging.info(message)
my_client = UMFuturesWebsocketClient(on_message=message_handler, proxies=proxies)
# Subscribe to a single symbol stream
my_client.agg_trade(symbol="bnbusdt")
time.sleep(5)
logging.info("closing ws connection")
my_client.stop()
```
#### Combined Streams
- If you set `is_combined` to `True`, `"/stream/"` will be appended to the `baseURL` to allow for Combining streams.
- `is_combined` defaults to `False` and `"/ws/"` (raw streams) will be appended to the `baseURL`.
More websocket examples are available in the `examples` folder
## Websocket < v4
```python
import time
from binance.websocket.um_futures.websocket_client import UMFuturesWebsocketClient
def message_handler(message):
print(message)
my_client = UMFuturesWebsocketClient(on_message=message_handler)
# Subscribe to a single symbol stream
my_client.agg_trade(symbol="bnbusdt")
time.sleep(5)
print("closing ws connection")
my_client.stop()
```
### Heartbeat
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.
