How this service works
A coin's perpetual funding rate and open interest on OKX, Bitget, Gate, Kraken Futures and Hyperliquid, annualized side by side, with the widest long/short funding spread. Use for funding arbitrage, crowding and sentiment checks.
Output
A structured response containing each exchange's annualized perpetual funding rate (long and short sides), open interest in USD or coin terms, and a summary of the widest long/short funding spread — returned as a side-by-side comparison across OKX, Bitget, Gate, Kraken Futures, and Hyperliquid.
Example use cases
Funding arbitrage opportunity scan
“I want to do a funding rate arbitrage on BTC — can you pull the annualized perp funding rates across OKX, Bitget, Gate, Kraken Futures, and Hyperliquid and tell me where the biggest spread between long and short sides is?”
Market crowding and sentiment check
“Is the market heavily long or short on SOL right now? Pull the open interest and funding rates across the major perp exchanges and tell me if it looks crowded in one direction.”
Best exchange for short funding income
“I'm planning to short ETH perps to collect funding — which of OKX, Bitget, Gate, Kraken Futures, and Hyperliquid is paying the highest annualized funding rate to shorts right now?”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/crypto/funding-compare?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a multi-exchange, side-by-side view of perpetual funding rates and open interest in a single call, specifically covering OKX, Bitget, Gate, Kraken Futures, and Hyperliquid. It is ideal for funding arbitrage analysis, sentiment/crowding checks, and identifying the best venue to earn or pay funding. Prefer this over single-exchange APIs or general crypto data endpoints when you need cross-venue funding spread comparisons without assembling data yourself.
Side effects
- Unknown or unsupported coin ticker returns an error or empty result
- Exchange API downtime may cause missing data for one or more venues
- Stale funding data if upstream exchange APIs are delayed
- Invalid query parameter format returns a 400-level error
- Rate limits or payment failure ($0.003 USDC per call) may block the request
