## When to prefer this

Use this endpoint when you need real-time, cross-exchange perpetual funding rate arbitrage data specifically between Hyperliquid and dYdX v4. It is ideal for delta-neutral arb strategies, crowded positioning detection, and annualized spread ranking. Prefer this over generic market data APIs when you need actionable cross-venue funding rate differentials with directional strategy recommendations rather than raw rate feeds.

## Known failure modes

- Invalid symbol ticker returns empty items array or no matching markets
- Limit out of range (below 1 or above 40) may return validation error
- Exchange data feed latency may cause stale or incomplete funding rate snapshots
- No arbitrage opportunities above threshold may return empty items
