## 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 hyperliquid-perp-oi-volume-leaderboard-1d8171a6
```

Example prompt: Show me the top 20 perp markets on Hyperliquid ranked by open interest — I want to see where leverage is concentrated, along with mark prices and hourly funding rates.

## When to prefer this

Use this endpoint when you need a ranked overview of leverage concentration across all Hyperliquid perpetual markets — ideal for macro positioning analysis, identifying high-funding-rate arbitrage targets, or understanding which coins are seeing the most speculative activity. Prefer this over single-coin orderbook depth endpoints when you need a cross-market leaderboard view rather than granular book data for one asset.

## Known failure modes

- Invalid sort parameter value returns an error or falls back to default OI sort
- Hyperliquid API unavailability causes upstream data fetch failure
- Stale data if the underlying Hyperliquid feed is delayed
- Payment failure (x402) blocks the request before it reaches the endpoint
