## 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-perpetuals-basis-funding-data-8a24f750 -d '<json body>'
```

Example prompt: Show me the top 10 Hyperliquid perpetuals ranked by most extreme funding rates — I want the mark vs oracle basis in basis points, hourly and annualized funding, and open interest so I can spot cash-and-carry opportunities.

## When to prefer this

Use this endpoint when you need real-time Hyperliquid perpetuals funding and basis data specifically — including mark vs oracle price spreads, basis points, hourly and annualized funding rates, and open interest — especially for basis trading, cash-and-carry strategy identification, or funding rate arbitrage. Prefer this over generic crypto APIs when you need the full funding rate breakdown (hourly + annualized) and basis in basis points in a single call, ranked by funding extremes.
