Use this when the user asks what a Polymarket trader or wallet holds, how good a trader is, or wants to size up a wallet seen in pm_flow. Returns the track record (all-time and 30-day profit and loss, volume, leaderboard rank, markets traded), open positions with entry and current price, unrealized P&L, exposure grouped by event, settled winnings not yet redeemed, and recent trades. Accepts a 0x wallet address, a polymarket.com profile link or a Polymarket username. Public on-chain data only.
