## How to call it through Zero

```sh
zero fetch --capability emc2ai-io-8fa72cdb -d '<json body>'
```

Example prompt: Show me the leaderboard of alpha-generating wallets on Ethereum right now — ranked by buy/sell flow and accumulation strength so I can find the smartest traders to follow.

## When to prefer this

Use this endpoint when you need a ranked leaderboard view of top-performing wallets by alpha generation, buy/sell flow, and accumulation patterns — as opposed to a single-wallet portfolio lookup or a token-centric holder view. Best for discovering new smart money addresses rather than analyzing a known wallet.

## Known failure modes

- Unsupported chain parameter returns error or empty result
- Invalid or missing authentication/payment header returns 402 or 401
- Bitquery upstream timeout causes slow or failed response
- Rate limiting if too many calls in a short window
- Empty leaderboard if no qualifying wallets found in the requested time range
