## 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 polynews-news-e29ea4f6 -d '<json body>'
```

Example prompt: Score the wallet 0xABC123... on Polymarket — give me the sharp score, any badges it's earned, the top trades, and overall P&L metrics.

## When to prefer this

Use this endpoint when you need a comprehensive performance profile of a single prediction market wallet — including a sharp score, badges, trade history highlights, and P&L — rather than broad market signals or multi-wallet smart money detection.

## Known failure modes

- Invalid or unrecognized wallet address returns 400 error
- Wallet with no trading history may return empty or zero-value metrics
- Network timeout if blockchain data is slow to resolve
- Payment failure via x402 protocol returns 402 status

## How this service works

Wallet performance scoring: sharp score, trader badge, top trades, and calibration metrics (alpha/Brier/conviction)

## Output

Returns a wallet performance scorecard including a numeric sharp score, earned badges (e.g. 'sharp', 'whale'), a list of top trades with outcomes, and aggregated P&L metrics such as ROI, win rate, and profit/loss totals.
