## 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 ai-rook-hyperliquid-whale-activity-feed-f69083ae
```

Example prompt: Pull the current whale activity feed from AI Rook's Hyperliquid endpoint — I want to see what large traders are doing on BTC perps right now, including whale CVD and any big order flow signals.

## When to prefer this

Choose this endpoint when you need real-time, whale-specific order flow data on Hyperliquid perpetuals rather than general market data. It is purpose-built for detecting large trader behavior on BTC perps with no API key or signup required, making it ideal for agents that need to quickly gauge institutional sentiment before executing trades or generating market reports.

## Known failure modes

- Payment not received — returns 402 if USDC payment on Base is not attached or insufficient
- Rate limit exceeded if free trial already consumed and no payment provided
- Hyperliquid API downtime may result in stale or unavailable data
- Malformed response if upstream data source is temporarily unavailable
