Example prompt: Can you scan Hyperliquid for funding rate arbitrage opportunities right now? Show me anything above a 0.05% threshold so I only see the most significant ones.

## When to prefer this

Use this endpoint when you need a real-time snapshot of Hyperliquid perpetual funding rate arbitrage opportunities, especially for building delta-neutral strategies or monitoring funding rate conditions. It is preferable when your focus is specifically on Hyperliquid rather than cross-exchange funding rate comparisons, and when you want filtered results by threshold rather than raw funding rate data for all markets.

## Known failure modes

- Empty opportunities array when no perps exceed the specified threshold — try lowering the threshold value
- Invalid threshold parameter type returns an error — must be a number
- Network or upstream Hyperliquid API unavailability causes request failure
- Threshold set too high (e.g. 1.0) will always return zero opportunities since funding rates are typically small decimals
