## When to prefer this

Use this endpoint when you need a quick, no-parameter snapshot of BTC, ETH, and SOL perpetual premiums versus oracle on Hyperliquid specifically. Prefer it over general funding rate endpoints when you care specifically about the mark-vs-oracle spread rather than hourly funding rates or open interest. Ideal for basis trading signals, sentiment analysis, or cross-exchange arbitrage detection.

## Known failure modes

- Hyperliquid API unavailable — worker returns 5xx error
- Stale or missing oracle data causing incorrect premium calculation
- Network timeout from the Cloudflare worker to upstream Hyperliquid data source
- Empty or malformed response if Hyperliquid market data feed is down
