## 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 market-intelligence-api-smart-money-wallets-871a27fa
```

Example prompt: Show me the top profitable DEX wallets for ETHUSD — I want to see their realized and unrealized PnL, win rates, holding times, and how their net flow compares to all wallets, excluding bots and MEV.

## When to prefer this

Choose this endpoint when you need to identify which specific on-chain wallets are profitably trading a given crypto asset and want to follow or benchmark against smart money. It is preferred over generic market signals when the goal is wallet-level attribution, PnL ranking, or copying successful trader behavior. The bot/MEV/arbitrage exclusion makes it more useful than raw on-chain flow data for identifying genuine informed traders.

## Known failure modes

- Invalid or unsupported symbol returns an error or empty result
- Symbol with insufficient on-chain trading activity may return few or no wallets
- Rate limiting or payment failure (x402) if USDC payment not attached
- Network timeout if DEX data aggregation is slow
- Stale data if the asset has low recent trading volume

## How this service works

Use to follow the traders who are actually making money on an asset. Returns the most profitable DEX wallets for a symbol (addresses only): realized and unrealized PnL, win rate, holding time, open position, and the recent net flow of the top wallets vs all wallets. Arbitrage, MEV, bots and routers excluded.

## Output

A list of wallet addresses ranked by profitability for the given symbol, each with realized PnL, unrealized PnL, win rate, average holding time, current open position size, plus an aggregate comparison of recent net flow between top wallets and all wallets on that asset. Arbitrage wallets, MEV bots, and routers are filtered out.
