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.
Output
A JSON object containing: skill_score (0–100, Sharpe-weighted by confidence), classification label (sharp/neutral/retail), win_rate, sample_size, max_drawdown, realized PnL, and unrealized PnL for the queried Polymarket wallet.
Example use cases

Technical details
Endpoint
POSThttps://graphadvocate.com/polymarket/pnl-quickWhen to prefer
Use this endpoint when you need a fast, lightweight skill assessment of a Polymarket wallet without full lot reconstruction — ideal for batch screening multiple holders before entering a market or deciding whether to copy a trade. Prefer the full PnL report endpoint when you need per-lot detail.
Side effects
- Wallet address not found or has no Polymarket activity — returns empty or low sample_size
- Invalid wallet format — 400 error
- Insufficient trade history for meaningful skill score — sample_size may be too small to trust classification
- Payment not processed — 402 error if x402 micropayment fails
- Endpoint timeout for wallets with very large trade histories
