Omnibook Python SDK

Official Python client for the Omnibook prediction market exchange. Sign up, create an API key, install this package, and trade.

pip install omnibook

from omnibook import Client

client = Client(api_key="<alphanumeric-api-key>", api_secret="<64-char-hex-secret>")

status = client.get_exchange_status()
rounds = client.get_rounds(limit=5)
order = client.place_order(
    client_order_id="42",
    market_id=66,
    side="buy",
    outcome="yes",
    type="limit",
    tick=47,
    qty=10,
    tif="gtc",
    post_only=True,
)

Prerequisites

  1. Sign in at omnibook.xyz.
  2. Deposit USDC (bot keys cannot withdraw).
  3. Create a key under Settings → API keys. Copy the API key and secret (the secret is shown once).

Environments

Env REST WebSocket
Production (default) https://api.omnibook.xyz wss://api.omnibook.xyz/v1/ws
Local http://127.0.0.1:9104 ws://127.0.0.1:9105/v1/ws

Sync and async

from omnibook import Client, AsyncClient

# Sync
with Client(api_key=..., api_secret=...) as client:
    print(client.get_balance())

# Async
async with AsyncClient(api_key=..., api_secret=...) as client:
    print(await client.get_balance())

WebSocket

from omnibook import Client

with Client(api_key=..., api_secret=...) as client:
    with client.websocket() as ws:
        ws.subscribe(channels=["rounds", "oracle", "user"])
        ws.subscribe(channels=["orderbook_delta", "trades"], market_ids=[66])
        for msg in ws:
            print(msg)

Auth note

Every request is HMAC-SHA256 signed. Settings hands you a 64-character hex secret (32 raw bytes). Pass that string (or a legacy base64 secret) to api_secret — the SDK hex-/base64-decodes it to the raw HMAC key for you.
