Quick Start

Basic Usage

from aion_sdk import AionMarketClient

# Initialize client
client = AionMarketClient()

# Register a new agent
registration = client.register_agent("my-trading-bot")
print(f"Agent API Key: {registration['apiKeyCode']}")

# Use authenticated client
api_key = registration['apiKeyCode']
client_auth = AionMarketClient(api_key=api_key)

# Get agent info
agent_info = client_auth.get_me()
print(f"Agent: {agent_info}")

Trading Example

from aion_sdk import AionMarketClient

client = AionMarketClient(api_key="your-api-key")

# Search for markets
markets = client.get_markets(q="bitcoin", limit=5)
print(f"Found {len(markets)} markets")

# Get market context before trading
if markets:
    market_id = markets[0]['id']
    context = client.get_market_context(market_id, user="0x...")
    print(f"Market: {context['name']}")
    print(f"Your position: {context['myPosition']}")
    print(f"Suggested risk limit: {context['riskLimit']}")

# Place a trade (Polymarket V2 — pUSD settlement)
# NOTE: V2 settles in pUSD (Polymarket's ERC-20 collateral token, backed by
#       USDC.e). Wallets must hold pUSD — wrap USDC.e → pUSD via the
#       CollateralOnramp contract first. V1 orders still settle in USDC.e
#       directly (legacy).

    },
})
print(f"Order placed: {result['orderId']}")

# Get open orders
open_orders = client.get_open_orders()
print(f"Open orders: {len(open_orders)}")

# Cancel an order
cancel_result = client.cancel_order(order_id=result.get('orderId', ''))
print(f"Cancelled: {cancel_result['success']}")

Wallet Credentials

from aion_sdk import AionMarketClient

client = AionMarketClient(api_key="your-api-key")

# Check if credentials are registered
wallet = "0x1234..."
check = client.check_wallet_credentials(wallet)
if not check['hasCredentials']:
    # Register credentials
    result = client.register_wallet_credentials(
        wallet_address=wallet,
        api_key="polymarket-api-key",
        api_secret="polymarket-api-secret",
        api_passphrase="polymarket-passphrase"
    )
    print(f"Credentials registered: {result['success']}")

Configuration

Base URL

The client defaults to production (https://api.aionmarket.com/bvapi). For staging, set the base URL:

client = AionMarketClient(
    api_key="your-api-key",
    base_url="https://pm-t1.bxingupdate.com/bvapi"
)

Timeout

Customize request timeout (default 20 seconds):

client = AionMarketClient(api_key="your-api-key", timeout=30)

Error Handling

from aion_sdk import AionMarketClient, ApiError

client = AionMarketClient(api_key="your-api-key")

try:
    result = client.get_me()
except ApiError as e:
    print(f"API Error: {e.message}")
    print(f"Status Code: {e.status_code}")
    print(f"Error Code: {e.code}")
    print(f"Raw Body: {e.response_body}")

Notes:

• SDK no longer strips response envelopes (success/data). You get the full JSON payload.
• For non-2xx responses, ApiError.response_body contains raw backend error JSON (for example detail, fix, hint, x402_url).
• You can call client.request(method, path, params=..., json=...) for passthrough access.
