## 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-wallet-tracker-feb85dec
```

Example prompt: Show me the smartest money on ETHUSD — which DEX wallets have the best realized PnL and win rate, and are the top traders currently net buying or selling?

## When to prefer this

Use this endpoint when you need to identify which on-chain traders are actually profitable on a specific asset and want to follow or replicate their positioning. Prefer this over generic order-flow or OHLCV endpoints when the goal is smart-money signal discovery, copytrading research, or understanding whether sophisticated DEX participants are accumulating or distributing. The bot/MEV/arbitrage filtering makes it uniquely suited for finding genuine discretionary or systematic alpha traders rather than noise.

## Known failure modes

- Symbol not in coverage list returns 404 (not charged)
- Invalid symbol format returns an error
- Symbol with insufficient on-chain data may return empty or sparse wallet list
- Network or API downtime returns 5xx errors
- Rate limit exceeded returns 429

## How this service works

Smart money wallets of a crypto asset: the most profitable DEX traders of a symbol (addresses only) with 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. Use to follow traders who make money.

## Output

A JSON response containing a ranked list of profitable DEX wallet addresses for the requested symbol, each with metrics including realized PnL, unrealized PnL, win rate, average holding time, and open position size. Also includes a comparison of recent net flow between the top wallets and all wallets for that symbol. Arbitrage wallets, MEV bots, and routers are excluded from results.
