How this service works
Call when an agent needs current perpetual funding for one symbol or a fixed major list. Tries Hyperliquid and Binance USDT-M futures, then OKX and Bybit. Includes next funding time and mark or index when the venue returns them. A geo-blocked venue is skipped. Send JSON {"symbol":"BTC"}. Exact $0.002 USDC on Base. Try unpaid POST /v1/sandbox/perp-funding-rates first.
Output
Returns current perpetual funding rate(s) per venue, next funding timestamp, and optionally mark or index price where the exchange provides them. Results are scoped to whichever venues are accessible (geo-blocked venues are silently skipped). Single symbol or up to 10 major assets depending on input.
Example use cases
Real-time BTC perp funding check
“Can you pull the current perpetual funding rate for BTC across Hyperliquid, Binance, and the other major venues? I want to see the next funding time too.”
Top 10 majors funding rate scan
“Show me the current funding rates for the top 10 major crypto perpetuals — I want to see which assets have the most extreme rates right now.”
Arbitrage opportunity screening
“Fetch current ETH perpetual funding rates across exchanges for me — I'm looking to see if there's a meaningful spread between venues to arb.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/perp-funding-rates?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time perpetual funding rate data aggregated across multiple top-tier venues (Hyperliquid, Binance, OKX, Bybit) in a single call. Ideal for trading agents that need to compare cross-venue funding, identify arbitrage spreads, or monitor carry costs. Prefer it over single-exchange APIs when multi-venue coverage and fallback resilience matter.
Side effects
- Symbol not found on any venue — returns empty or error response
- All venues geo-blocked from the server's region — returns no data
- Invalid symbol format — rejected with validation error
- Rate limit or upstream exchange downtime — partial or empty results
- Limit exceeds maximum of 10 — clamped or rejected
