# Binance Public API Connector Python
[](https://pypi.python.org/pypi/binance-connector.svg)
[](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
- 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()
print(client.time())
client = Spot(key='<api_key>', secret='<api_secret>')
# Get account 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.
### 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(key, 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 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
```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()
```
More websocket examples are available in the `examples` folder
### 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
