ito-markets — Python SDK for Ito Markets

Thin, typed Python wrapper for the Ito Markets public API. Access prediction market baskets, individual market data, historical orderbook snapshots, and run backtests — all with a single pip install.

Install

pip install ito-markets
# or with pandas support:
pip install ito-markets[pandas]

Quick Start

from ito import ItoClient

client = ItoClient("ito_...")  # your API key from Settings

# List all baskets
baskets = client.baskets.list()
for b in baskets["data"]:
    print(f"{b['basket_id']}: ${b['stats']['current_price']:.2f}")

# Get a single market
market = client.markets.get("will-btc-reach-100k")
print(market["data"]["title"], market["data"]["last_price"])

# Price history
history = client.markets.history("will-btc-reach-100k", days=90)
for point in history["data"]["series"]:
    print(point["date"], point["close_price"])

# Bulk prices for multiple markets
prices = client.data.prices(["market-a", "market-b", "market-c"], days=30)

# Historical L2 orderbook
book = client.data.orderbook(
    venue="polymarket",
    market="will-btc-reach-100k",
    start="2026-06-01T00:00:00Z",
    end="2026-06-01T01:00:00Z",
    limit=5000,
)

# Run a backtest on a thematic basket
result = client.backtests.run(
    strategy_id="crypto_updown_roll_timing",
    dataset_id="clickhouse:ito_hot.platform_orderbook_l2",
    venues=["polymarket"],
    date_range={"start": "2026-05-01T00:00:00Z", "end": "2026-06-01T00:00:00Z"},
    basket_id="middle-east-conflict",  # only markets in this basket
    params={"roll_trigger": "liquidity_spread_score"},
)
print(f"P&L: ${result['data']['metrics']['pnl_usd']:.2f}")
