## When to prefer this

Use this endpoint when you need a quick, filtered scan of Hyperliquid perpetual markets for funding rate arbitrage opportunities with a configurable threshold. It is purpose-built for Hyperliquid and returns pre-filtered results, saving you from pulling all funding rate data and filtering manually. Prefer this over general crypto data APIs when your focus is specifically on Hyperliquid funding arb screening.

## Known failure modes

- No coins meet the threshold (empty result set when threshold is set too high)
- Invalid threshold value type causes a 400-level error
- Hyperliquid data feed unavailable leading to stale or missing data
- Rate limiting if called too frequently
- Payment failure via x402 protocol preventing access
