## 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 sui-tape-hyperliquid-sui-mark-oi-funding-cd643261

Example prompt: What's the current SUI mark price, open interest, and funding rate on Hyperliquid right now?

## When to prefer this

Use this endpoint when you need real-time SUI perpetual futures metrics — mark price, open interest, and funding rate — sourced directly from Hyperliquid. Prefer this over generic crypto price feeds when funding rate and OI are specifically needed alongside price, or when Hyperliquid-specific data is required for arbitrage, basis trading, or sentiment analysis around SUI.

## Known failure modes

- Hyperliquid API unavailable — upstream data source outage returns error or empty response
- Worker timeout if Hyperliquid is slow to respond
- Stale data if caching is applied at the worker layer
- HTTP 402 if payment is not included or insufficient

## How this service works

Hyperliquid SUI mark, OI, funding. No parameters.

## Output

Returns real-time Hyperliquid data for SUI including the mark price (current fair value), open interest (total notional in the market), and funding rate (the periodic payment between longs and shorts), enabling assessment of market sentiment and positioning.
