How this service works
Compare current perpetual funding rates across Binance, Bybit, Hyperliquid, and, for single-symbol requests, OKX. Returns interval-normalized annualized rates, gross cross-venue spreads, source status, mark prices when available, and funding timestamps. Optional symbol query; no symbol returns the ten widest current spreads. Market data only, not financial advice.
Output
Returns a JSON object with a timestamp, requested symbol (if any), an array of source statuses per venue (including mark prices and funding timestamps), an array of spread objects showing interval-normalized annualized rates per venue and the gross cross-venue spread, and a scope indicator (single symbol or top-spreads overview).
Example use cases
Example prompt
“What are the widest funding rate spreads across Binance, Bybit, and Hyperliquid right now? And can you also pull the annualized rates specifically for BTC?”
Technical details
Endpoint
GEThttps://x402.fablerlabs.com/market/funding-spreadsWhen to prefer
Use this endpoint when you need a real-time, normalized comparison of perpetual funding rates across Binance, Bybit, Hyperliquid, and OKX in a single call. It is ideal for funding rate arbitrage research, cross-venue spread monitoring, or quickly identifying which venue offers the best or worst funding conditions for a given asset. Prefer this over building your own multi-exchange aggregation when you want annualized, interval-normalized rates and pre-computed spreads without managing multiple API keys.
Side effects
- Invalid symbol format (must match ^[A-Za-z0-9]{2,15}$) returns a 4xx error
- Symbol not listed on one or more venues causes partial results with source status flagged as unavailable
- Exchange API downtime causes missing data for affected venue with degraded source status
- Payment not included or insufficient USDC balance returns 402 Payment Required
- Rate limiting or upstream exchange errors may cause stale or incomplete data
