Asyncronous Python REST and WebSocket Clients for Coinbase Pro
The CoPrA (Coinbase Pro Async) package provides asyncronous REST and WebSocket clients written in Python for use with the Coinbase Pro digital currency trading platform. To learn about Coinbase Pro's REST and WebSocket APIs as well as how to obtain an API key for authentication to those services, please see Coinbase Pro's API documentation.
- compatible with Python 3.5 or greater
- utilizes Python's asyncio concurrency framework
- open source (MIT license)
- Asyncronous REST client class with 100% of the account management, trading, and market data functionality offered by the Coinbase Pro REST API.
- supports user authentication
- built on aiohttp, the asynchronous HTTP client/server framework for asyncio and Python
- Asyncronous WebSocket client class with callback hooks for managing every phase of a Coinbase Pro WebSocket session
- supports user authentication
- built on Autobahn|Python, the open-source (MIT) real-time framework for web, mobile & the Internet of Things.
Without a Coinbase Pro API key, copra.rest.Client has access to all of the public market data that Coinbase makes available.
# 24hour_stats.py
import asyncio
from copra.rest import Client
loop = asyncio.get_event_loop()
client = Client(loop)
async def get_stats():
btc_stats = await client.get_24hour_stats('BTC-USD')
print(btc_stats)
loop.run_until_complete(get_stats())
loop.run_until_complete(client.close())Running the above:
$ python3 24hour_stats.py
{'open': '3914.96000000', 'high': '3957.10000000', 'low': '3508.00000000', 'volume': '37134.10720409', 'last': '3670.06000000', 'volume_30day': '423047.53794129'}In conjunction with a Coinbase Pro API key, copra.rest.Client can be used to trade cryptocurrency and manage your Coinbase pro account. This example also shows how copra.rest.Client can be used as a context manager.
# btc_account_info.py
import asyncio
from copra.rest import Client
KEY = YOUR_API_KEY
SECRET = YOUR_API_SECRET
PASSPHRASE = YOUR_API_PASSPHRASE
BTC_ACCOUNT_ID = YOUR_BTC_ACCOUNT_ID
loop = asyncio.get_event_loop()
async def get_btc_account():
async with Client(loop, auth=True, key=KEY,
secret=SECRET, passphrase=PASSPHRASE) as client:
btc_account = await client.account(BTC_ACCOUNT_ID)
print(btc_account)
loop.run_until_complete(get_btc_account())Running the above:
$ python3 btc_account_info.py
{'id': '1b121cbe-bd4-4c42-9e31-7047632fc7c7', 'currency': 'BTC', 'balance': '26.1023109600000000', 'available': '26.09731096', 'hold': '0.0050000000000000', 'profile_id': '151d9abd-abcc-4597-ae40-b6286d72a0bd'}While copra.websocket.Client is meant to be overridden, but it can be used 'as is' to test the module through the command line.
# btc_heartbeat.py
import asyncio
from copra.websocket import Channel, Client
loop = asyncio.get_event_loop()
ws = Client(loop, Channel('heartbeat', 'BTC-USD'))
try:
loop.run_forever()
except KeyboardInterrupt:
loop.run_until_complete(ws.close())
loop.close()Running the above:
$ python3 btc_heartbeat.py
{'type': 'subscriptions', 'channels': [{'name': 'heartbeat', 'product_ids': ['BTC-USD']}]}

.A Coinbase Pro API key allows copra.websocket.Client to authenticate with the Coinbase WebSocket server giving you access to feeds specific to your user account.
