⚡ Quick Start

Here's how to get started with the async Zex client in just a few lines of code.

import asyncio
from zex.sdk import AsyncClient

async def main():
    # Create a Zex client instance (testnet is True by default)
    client = await AsyncClient.create(api_key="your-api-key")

    # Example: get the price of ETH/USDT
    price = await client.get_price("ETH-USDT")
    print("Current price:", price)

asyncio.run(main())

Note: Use AsyncClient.create(...) instead of the constructor. It handles registration and setup for you.

📘 Usage Examples

Here are some common usage examples using the AsyncClient and ZexSocketManager.

---

✅ Place a Batch of Orders

from zex_sdk.models import PlaceOrderRequest, OrderSide

orders = [
    PlaceOrderRequest(
        base_token="ETH",
        quote_token="USDT",
        side=OrderSide.BUY,
        volume=0.5,
        price=1900.0
    ),
    PlaceOrderRequest(
        base_token="BTC",
        quote_token="USDT",
        side=OrderSide.SELL,
        volume=0.1,
        price=30000.0
    ),
]

await client.place_batch_order(orders)

---

❌ Cancel a Batch of Orders

# Suppose you have stored signed orders
signed_orders = [...] # List[bytes]

await client.cancel_batch_order(signed_orders)

---

📈 Get Current Market Price

price = await client.get_price("ETH-USDT")
print("ETH price:", price)

---

🔔 Listen to Execution Reports in Real-Time

from zex_sdk.socket import ZexSocketManager

async def on_execution_report(message):
    print("Execution report received:", message)

socket_manager = ZexSocketManager(client)

# Use async context manager to open and manage the socket
async with await socket_manager.execution_report_socket(on_execution_report):
await asyncio.sleep(60) # keep listening for 60 seconds
