## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability graphadvocate-com-4f1d0b5b -d '<json body>'
```

Example prompt: Score this Polymarket wallet 0xAbC123... for me — is it a sharp, neutral, or retail trader? I want the skill score, win rate, and max drawdown before I decide whether to mirror their positions.

## When to prefer this

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.

## Known failure modes

- 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

## How this service works

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.

## 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.
