# Binance Public API Connector Python
[](https://pypi.python.org/pypi/binance-connector)
[](https://www.python.org/downloads/)
[](https://binance-connector.readthedocs.io/en/stable/)
[](https://black.readthedocs.io/en/stable/)
[](https://opensource.org/licenses/MIT)
This is a lightweight library that works as a connector to [Binance public API](https://github.com/binance/binance-spot-api-docs)
- Supported APIs:
- `/api/*`
- `/sapi/*`
- Spot Websocket Market Stream
- Spot User Data Stream
- Spot WebSocket API
- Inclusion of test cases and examples
- Customizable base URL, request timeout and HTTP proxy
- Response metadata can be displayed
## Installation
```bash
pip install binance-connector
```
## Documentation
[https://binance-connector.readthedocs.io](https://binance-connector.readthedocs.io)
## RESTful APIs
Usage examples:
```python
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.
- In order to set your API and Secret Key for use of the examples, create a file `examples/config.ini` with your keys.
- Eg:
```ini
# examples/config.ini
[keys]
api_key=abc123456
api_secret=cba654321
```
### Authentication
Binance supports HMAC and RSA API authentication.
```python
# 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.
### Testnet
[Spot Testnet](https://testnet.binance.vision/) 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](https://dev.binance.vision/t/99)
To use testnet:
```python
from binance.spot import Spot as Client
client = Client(base_url='https://testnet.binance.vision')
print(client.time())
```
### Base URL
If `base_url` is not provided, it defaults to `api.binance.com`.<br/>
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`
### 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.cancel_oco_order('BTCUSDT', orderListId=1)
# Unrecognised parameter name
response = client.cancel_oco_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.spot import Spot as Client
client = Client(api_key, api_secret)
response = client.get_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.spot import Spot as Client
client= Client(timeout=1)
```
### Proxy
Proxy is supported.
```python
from binance.spot import Spot as Client
proxies = { 'https': 'http://1.2.3.4:8080' }
client= Client(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.spot import Spot as Client
client = Client(show_limit_usage=True)
print(client.time())
```
returns:
```python
{'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:
```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 5 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.
- `error_data`* - Additional detailed data which supplements the `error_message`.
- **Only applicable on select endpoints, eg. `cancelReplace`*
- `binance.error.ServerError`
- This is thrown when server returns `5XX`, it's an issue from server side.
## Websocket
### Connector v3
WebSocket can be established through either of the following types of connections:
- WebSocket API (`https://github.com/binance/binance-spot-api-docs/blob/master/web-socket-api.md`)
- WebSocket Stream (`https://github.com/binance/binance-spot-api-docs/blob/master/web-socket-streams.md`)
```python
# WebSocket API Client
from binance.websocket.spot.websocket_api import SpotWebsocketAPIClient
def message_handler(_, message):
logging.info(message)
my_client = SpotWebsocketAPIClient(on_message=message_handler)
my_client.ticker(symbol="BNBBUSD", type="FULL")
time.sleep(5)
logging.info("closing ws connection")
my_client.stop()
```
```python
# WebSocket Stream Client
from binance.websocket.spot.websocket_stream import SpotWebsocketStreamClient
def message_handler(_, message):
logging.info(message)
my_client = SpotWebsocketStreamClient(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.ping_connectivity(id="my_request_id")
# library will generate a random uuid string
my_client.ping_connectivity()
```
More websocket examples are available in the `examples` folder.
Example file "examples/websocket_api/app_demo.py" demonstrates how Websocket API and Websocket Stream can be used together.
### Connector v1 and v2
```python
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()
```
### 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.
### Testnet
```python
from binance.websocket.spot.websocket_client import SpotWebsocketClient as WebsocketClient
ws_client = WebsocketClient(stream_url='wss://testnet.binance.vision')
```
## Test Case
```python
# In case packages are not installed yet
pip install -r requirements/requirements-test.txt
pytest
```
## Limitation
Futures and Vanilla Options APIs are not supported:
- `/fapi/*`
- `/dapi/*`
- `/vapi/*`
- Associated Websocket Market and User Data Streams
