## 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-b450a89c -d '<json body>'
```

Example prompt: Show me the leaderboard of top smart money wallets on Ethereum right now — I want to see their buy and sell flows and which ones are accumulating.

## When to prefer this

Use this endpoint when you need a ranked, leaderboard-style view of the best-performing on-chain traders with buy/sell flow breakdown. Prefer this over token-centric endpoints when the focus is on which wallets (not which tokens) are moving capital. It is distinct from the capital-intensive traders endpoint in that it ranks by accumulation patterns and flow balance, not just raw trade size.

## Known failure modes

- Unsupported chain specified returns error or empty result
- Missing required chain or filter parameter causes 400-style error
- Payment of 0.85 USDC not fulfilled results in 402 Payment Required
- Bitquery upstream timeout returns partial or no data
- Invalid wallet address filter returns empty leaderboard
