How this service works
Crypto perpetual funding rates and open interest ($0.001): latest annualised funding rate and open interest of perp markets on Hyperliquid (crypto plus stock, index, gold, oil and FX perps), GMX v2 and gTrade, largest funding first. Use to spot crowded leverage cheaply.
Output
A ranked list of perpetual markets (crypto, FX, commodities, tokenized indices/stocks) with their latest annualised funding rate and open interest, sorted descending by funding rate, covering Hyperliquid, GMX v2, and gTrade.
Example use cases
Spotting crowded leverage before a trade
“Before I open a long on ETH perps, can you pull the latest funding rates and open interest across Hyperliquid, GMX v2, and gTrade so I can see if longs are already overcrowded and the funding cost will eat into my position?”
Funding rate arbitrage signal scan
“Pull the annualised funding rates for all perp markets right now — crypto, FX, gold, oil, everything — sorted highest first. I want to find pairs where there's a big spread between venues I could arb.”
Daily market positioning briefing
“Give me a quick morning briefing on where leverage is most concentrated across decentralised perp markets — show me funding rates and open interest on Hyperliquid, GMX, and gTrade, biggest funding rate at the top.”

Endpoint
GEThttps://api.marketintelligenceapi.com/api/v1/markets/funding-rates?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a unified, cross-exchange view of perpetual market funding rates and open interest in a single cheap call ($0.001). It is especially valuable for identifying crowded leverage, funding rate arbitrage opportunities, or assessing the cost of holding a perp position across Hyperliquid, GMX v2, and gTrade simultaneously — including non-crypto perps like FX, gold, oil, and tokenized indices.
Side effects
- Stale data if underlying DEX APIs are delayed or experiencing downtime
- Empty or partial response if one of the three exchanges (Hyperliquid, GMX v2, gTrade) is temporarily unreachable
- Payment required error (402) if the x402 micropayment of $0.001 USDC is not provided
- Rate limiting if the endpoint is called too frequently without valid payment headers
