## 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-funding-rates-open-interest-4ceb4f83
```

Example prompt: Show me the top 20 Hyperliquid perps ranked by open interest, including their hourly funding rate, annualized APR, mark price, and max leverage — I want to spot funding arbitrage opportunities.

## When to prefer this

Choose this endpoint when you need real-time perpetual futures market data specifically from Hyperliquid — funding rates, open interest rankings, or leverage info — for use cases like funding arbitrage, basis trading, or leverage sentiment analysis. Prefer this over generic crypto price endpoints when the derivative market structure (funding, OI, leverage) is what matters, not just spot price.

## Known failure modes

- Invalid sort value returns an error or empty response
- Requesting an unknown coin symbol returns no data for that symbol
- Limit out of range (outside 1-300) may return an error
- Hyperliquid API unavailability causes upstream fetch failure
- Network timeout from the render.com host under load
