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

## When to prefer this

Use this endpoint when you specifically need real-time UNI perpetual futures data (mark price, OI, funding) from Hyperliquid. Prefer this over generic market data APIs when Hyperliquid-specific funding rates and OI are required, for example to assess arbitrage opportunities or track crowding in UNI perp positions.

## Known failure modes

- Hyperliquid API unavailable — upstream fetch fails, returns 5xx error
- Stale data if Hyperliquid feed is delayed
- Network timeout from Cloudflare Worker if Hyperliquid is slow to respond
- Unexpected schema changes from Hyperliquid breaking the parser

## How this service works

Hyperliquid UNI mark, OI, funding. No parameters.

## Output

Returns UNI perpetual market data from Hyperliquid including the mark price (in USD), total open interest (in USD or contracts), and the current funding rate (as a percentage or basis points), typically as a JSON object with those three fields.
