## 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 coinank-big-order-list-46d73b05
```

Example prompt: Show me the latest large buy orders for BTCUSDT on Binance — I want to see whale-sized trades coming through right now.

## When to prefer this

Use this endpoint when you need to track large cryptocurrency orders (whale activity) on specific exchanges, filter by buy/sell side, symbol, or minimum order size/amount. Ideal for market analysis agents monitoring institutional order flow or large trades in real time or historically.

## Known failure modes

- Empty data array if no big orders match the given filters
- Invalid symbol or exchange parameter returns error or empty result
- Payment failure (402) if USDC wallet balance is insufficient
- Malformed query parameters may result in no results or API error
- startTime in wrong format may return empty or incorrect historical data
