## 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 emc2ai-io-73b7c9fe -d '<json body>'
```

Example prompt: Show me the top smart money traders on Ethereum right now — I want to see their buy and sell flows and which wallets have the strongest accumulation patterns.

## When to prefer this

Use this endpoint when you need to identify which wallet addresses are the most active or profitable traders on a given blockchain, especially when you want buy/sell flow breakdowns and accumulation signals. Prefer this over token-centric endpoints when the goal is to rank traders rather than analyze a specific token's holders.

## Known failure modes

- Unsupported chain specified returns an error or empty result
- Invalid or missing chain parameter causes 400-level error
- Rate limits or payment failure returns 402 or 429
- No significant smart money activity in the queried period returns empty leaderboard
- Bitquery upstream timeout results in delayed or null response
