Tools

attest_agent ~166 tokens
Submit the signed attestation. Returns a 30-day agent token that unlocks gasless Polymarket account setup through predictDEX's signer for your address only. It grants no custody and no exemption from region rules.
create_trade_link Moves money · ~228 tokens
A pre-filled predictDEX ticket URL (event, market, outcome, side, amount) for a person to review and sign in their own wallet. Opening it executes nothing. Use this when you have no wallet or need human confirmation.
get_agent_challenge ~108 tokens
Returns the canonical 'predictDEX Agent Attestation v1' message for your address. Sign it with EIP-191 personal_sign within 10 minutes and pass it to attest_agent.
get_event ~142 tokens
Full event by slug: every market, outcome names and prices, token ids, tick size, min order size, rules summary, resolution source and status. Optionally include recent trades.
get_leaderboard ~132 tokens
Top Polymarket traders by profit or volume over a window.
get_orderbook ~128 tokens
Live order book for one outcome token: bids and asks (price 0-1, size in shares), spread, midpoint and last trade.
get_positions ~99 tokens
Open positions of a Polymarket trading account or its owner address: size, average price, current price, value and P&L.
get_price_history ~104 tokens
Price (probability) history for one outcome token over a range.
get_trading_setup ~110 tokens
Everything an agent with its own wallet needs to trade: chain, collateral (pUSD), builder code, signer URL, attestation steps, fees and a ready-to-run TypeScript snippet using Polymarket's official SDK. Non-custodial: you sign with your own key.
quote_order ~366 tokens
Preview an order against the live book without placing it: average and worst price, shares, cost, payout if the outcome wins, Polymarket fee, predictDEX fee and warnings. Market BUY amount is USD to spend all-in; market SELL and limit amounts are shares.
search_markets ~317 tokens
Find events and their markets with live odds. Filter by free-text query, category slug (see predict://categories), sort and status. Each event lists markets with outcomes, token ids, best bid/ask, tick size and a human URL.
