## 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 agent-collabrachain-fun-abb1ebab -d '<json body>'
```

Example prompt: Show me the top Polymarket whale traders ranked by profitability over the last 30 days — I want to see who the biggest winners are, their win rates, and what strategies they're using.

## When to prefer this

Use this endpoint when you need a ranked list of top Polymarket traders across a defined time window. Prefer this over individual whale profile endpoints when you want comparative leaderboard data rather than deep analysis of a single trader. Ideal for discovering which traders to follow or emulate without knowing specific wallet addresses.

## Known failure modes

- Invalid period value (not 7d, 30d, or overall) returns validation error
- Payment not included or insufficient USDC results in 402 Payment Required
- Polymarket data temporarily unavailable returns 503 or empty leaderboard
- Network timeout if upstream Polymarket data fetch is slow
