## How to call it through Zero

## When to prefer this

Use this endpoint when you specifically need XRP perpetual market data (mark price, OI, funding) sourced from Hyperliquid. Prefer it over generic exchange APIs when you want Hyperliquid-specific funding rates for arbitrage or sentiment analysis. Choose sibling endpoints (ARB Tape, ETH BTC Ratio, etc.) for other assets.

## Known failure modes

- Hyperliquid API unavailable — upstream outage causes empty or error response
- Worker service timeout — haiqingm58.workers.dev may return 5xx under load
- Stale data — if upstream feed lags, returned values may not reflect latest market state
- Payment failure — x402 micropayment not processed, endpoint returns 402

## How this service works
