Arkham Exchange Python SDK

A Python client library for the Arkham Exchange API, providing both REST and WebSocket interfaces for trading cryptocurrency and managing your account.

Installation

Install the SDK using pip:

pip install arkham-sdk-python

Basic Usage

REST API Client

from arkham_sdk_python.client import Arkham

# Initialize the client with your API credentials
client = Arkham(
    api_key="your_api_key",
    api_secret="your_api_secret"
)

# Get trading pairs
pairs = client.get_pairs()
print(f"Available pairs: {pairs}")

# Get order book for a specific pair
orderbook = client.get_orderbook(symbol="BTC_USDT")
print(f"Order book: {orderbook}")

# Place a limit order
order = client.create_order(
    {
        "symbol": "BTC_USDT",
        "side": OrderSide.Buy,
        "type": OrderType.LimitGtc,
        "size": "0.0001",
        "price": "30000",
    }
)
print(f"Order placed: {order}")

WebSocket Client

from arkham_sdk_python.ws_client import ArkhamWebSocket
from arkham_sdk_python.models import WebsocketTradesUpdate

def handle_trade_update(update: WebsocketTradesUpdate):
    print(f"Trade update: {update}")

# Initialize WebSocket client
ws = ArkhamWebSocket(
    api_key="your_api_key",
    api_secret="your_api_secret"
)

# Connect and subscribe to trades
ws.connect()
ws.subscribe_trades("BTC-USD", handle_trade_update)

# Keep the connection alive
try:
    ws.wait()
except KeyboardInterrupt:
    ws.close()

Authentication

The SDK requires API credentials to access private endpoints:

1. API Key: Your unique API key from Arkham Exchange
2. API Secret: Your secret key for signing requests

You can obtain these credentials from your Arkham Exchange account dashboard.
