What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

• get_market

  Full details of one market, including its rules and the ids of its up and down outcome tokens.

• get_order_book

  Order book of a market outcome: bids (best first) and asks with prices in USDC per token and sizes in tokens, plus best bid, best ask and mid. Buying down at p is the same book as selling up at 1 - p.

• get_pnl_history

  Profit and loss over time of a wallet, as a series of points. Defaults to the configured wallet.

• get_positions

  Positions of a wallet: tokens held per market and outcome, average price, current value and profit. Settled markets show the payout. Defaults to the configured wallet.

• get_status

  Health of the Lucyd service: API and database, settlement of ended markets on time, live trade stream. Use it when something looks stuck, e.g. a market is not resolving.

• get_trader_stats

  Stats of a wallet: total and realized profit, volume, markets traded, win rate. Defaults to the configured wallet.

• list_markets

  List prediction markets on Lucyd. Each market asks whether the BTC price will be Up or Down at its end date versus the strike (strike is the price times 1e8). Returns address (the market id), state, period, start and end dates, strike, winner and volume.

• list_trades

  Recent trades, newest first. Filter by market and/or trader. Amounts are in USDC and tokens.

• top_traders

  Leaderboard of traders, best first.
