## How to call it through Zero

```sh
zero fetch --capability zatena-smart-money-whale-tracker-37ab682b
```

Example prompt: Show me the top smart-money whale wallets ranked by their realized P&L, win rate, and activity score — I want to see their current on-chain positions too so I can figure out which traders to follow.

## When to prefer this

Use this endpoint when you need a ready-made leaderboard of high-performing on-chain traders, particularly those active in prediction markets like Polymarket, and want their composite smart-money score along with live position exposure — rather than building your own ranking logic from raw transaction data.

## Known failure modes

- 402 Payment Required if x402 payment header is missing or insufficient
- Empty or stale whale list if no wallets meet the ranking threshold
- Network timeout if on-chain position data is slow to resolve
- Malformed response if upstream indexer is unavailable

## How this service works

Top smart-money wallets ranked by realized P&L x win rate x activity, with their current on-chain positions

## Output

A JSON array of top whale wallets, each with their wallet address, win rate (0–1), smart money composite score, total realized P&L, number of markets traded, and a list of current on-chain positions (token ID, position title, and net size).
