How this service works
Hyperliquid perp funding (hourly + APR), open interest (coins + USD), mark/oracle/mid px, 24h volume for BTC, ETH, SOL. Optional coin=BTC.

Example use cases
Funding rate arbitrage signal
“Check the current Hyperliquid funding rate for BTC perps — I want to know the hourly rate and the annualized APR so I can decide whether to go long or short to capture funding.”
Open interest trend monitoring
“What's the total open interest in SOL perpetuals on Hyperliquid right now, both in coin terms and in USD? I'm trying to gauge how much leverage is in the market.”
Mark vs oracle price divergence check
“Pull the mark price and oracle price for ETH on Hyperliquid — I want to see if there's a significant divergence between them right now.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/crypto/hl-funding?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time Hyperliquid-specific perpetual funding rates and open interest for BTC, ETH, or SOL — particularly for onchain AI agents that can pay micro-fees via x402/USDC on Base. Prefer this over generic market data APIs when you specifically need Hyperliquid venue data including funding APR, mark vs oracle price spread, and USD-denominated open interest in a single lightweight call.
Side effects
- Invalid coin parameter (not BTC/ETH/SOL) returns 400 error
- Hyperliquid upstream API unavailable causes 502/503
- Payment not included or insufficient USDC on Base triggers 402 Payment Required
- Rate limiting if too many calls in rapid succession
- Stale data if Hyperliquid feed is delayed
