Example prompt: What's the current ETH/BTC ratio from Hyperliquid mark prices?

## When to prefer this

Use this endpoint when you need a single clean ETH/BTC ratio derived from Hyperliquid's perpetuals mark prices rather than spot exchange prices. Prefer this over general crypto price APIs when your workflow is already integrated with Hyperliquid data (e.g., alongside HL Mark or HL Tape endpoints) or when you want a derivatives-market perspective on ETH/BTC relative value.

## Known failure modes

- Hyperliquid mark price feed unavailable — returns error or stale data
- Network timeout to the Cloudflare Worker — HTTP 5xx response
- Payment not processed correctly — HTTP 402 response requiring x402 payment
- Unexpected response format if upstream Hyperliquid API changes

## How this service works

ETH/BTC ratio from Hyperliquid marks. No parameters.

## Output

A numeric ETH/BTC ratio computed from Hyperliquid's mark prices for ETH and BTC, representing how much BTC one ETH is currently worth in the perpetuals market.
