Polymarket trader skill score — pure JSON for agents. POST {wallet}. Returns skill_score (0-100, Sharpe-weighted by confidence), classification (sharp/neutral/retail), win_rate, sample_size, max_drawdown, realized + unrealized PnL. No lot reconstruction — for batch screening top holders before entering a market or mirroring a copy-trade.
