How this service works
Perpetual-swap funding rates for an asset fused across decentralized venues (Hyperliquid, dYdX v4): each venue's current funding plus an open-interest weighted aggregate funding rate, annualized APR, the cross-venue spread and dispersion. One normalized call instead of polling each protocol and reconciling funding intervals yourself.
Output
A JSON object containing: each venue's (Hyperliquid, dYdX v4) current funding rate, the open-interest-weighted aggregate funding rate, the annualized APR of that aggregate, the cross-venue spread (difference between highest and lowest venue rate), and dispersion metric — all normalized to a common interval for direct comparison.
Example use cases
Funding arbitrage opportunity detection
“Check the cross-venue funding spread for BTC perps between Hyperliquid and dYdX — I want to know if there's a meaningful disparity worth arbitraging right now.”
Carry trade APR estimation
“What's the annualized funding APR for SOL perpetual swaps aggregated across DeFi venues? I'm trying to figure out if a long spot / short perp carry trade makes sense.”
Real-time funding dashboard update
“Pull the latest funding rates for ETH across all supported decentralized perp venues, including the aggregate weighted rate and any cross-venue dispersion.”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/derivs/fundingWhen to prefer
Use this endpoint when you need a single, normalized view of perpetual funding rates across multiple decentralized venues (Hyperliquid, dYdX v4) without writing your own polling, interval-reconciliation, or aggregation logic. Prefer it over querying each protocol directly when you want cross-venue spread, dispersion, or an OI-weighted aggregate in one call.
Side effects
- Unsupported symbol returns an error or empty result (e.g. obscure altcoins not listed on both venues)
- Venue API downtime may cause partial results or stale data for that venue
- Malformed symbol not normalized correctly may return 400 or empty response
- Network timeouts to upstream protocols may cause latency spikes or failures
