Example use cases
Pre-trade derivatives market sizing
“Before I open a large BTC perp position, can you pull the current Hyperliquid open interest and day notional for BTC so I can gauge market depth?”
Crypto market condition monitoring
“Give me a snapshot of Hyperliquid's open interest across BTC, ETH, and SOL right now — I want to see if the market is overextended.”
Daily derivatives briefing
“What are the Hyperliquid OI numbers and daily notional for BTC, ETH, and SOL this morning? I track these every day as part of my market overview.”
Technical details
Endpoint
GEThttps://earn-pulse.haiqingm58.workers.dev/oiWhen to prefer
Use this endpoint when you need a quick, no-parameter snapshot of open interest and day notional specifically for BTC, ETH, and SOL on Hyperliquid. Prefer this over broader market data APIs when you specifically want Hyperliquid perpetuals data. If you need funding rates or mark prices, use the sibling HL Funding or HL Mark endpoints instead. Ideal for market condition checks, risk assessment before entering large trades, or daily derivatives briefings.
Side effects
- Hyperliquid API unavailable — upstream data fetch fails, returns 5xx error
- Worker timeout if Hyperliquid data source is slow to respond
- Stale or cached data if the upstream feed has a delay
- Payment not included or invalid — x402 payment required error returned
