Endpoint
GEThttps://earn-pulse.haiqingm58.workers.dev/arbWhen to prefer
Use this endpoint when you need a quick, no-parameter snapshot of ARB perpetual market conditions (mark price, OI, funding) sourced directly from Hyperliquid. Prefer it over generic market data APIs when Hyperliquid-specific funding and OI accuracy matters, especially for DeFi yield strategies or perp trading decisions on that venue.
Side effects
- Hyperliquid API unavailable — upstream 5xx propagated
- Worker timeout if Hyperliquid response is slow
- Stale data if Hyperliquid feed lags
- Payment failure if x402 USDC payment not settled
