How this service works
Pre-trade funding check for perp positions: one call aggregates live funding across Hyperliquid + dYdX + Aevo for a ticker (BTC, ETH, SOL, …). Per-venue 8h funding, annualized APR, open interest USD, mark price, and cross-venue median APR. Spot delta-neutral carry or skewed funding before opening a position. Cached 30s.
Output
Returns a JSON object with per-venue data (8h funding rate, annualized APR, open interest in USD, mark price) for each of Hyperliquid, dYdX, and Aevo, plus a cross-venue median APR for the requested ticker. Data is cached for 30 seconds.
Example use cases
Best venue for BTC carry
“I'm about to open a BTC delta-neutral carry trade — can you pull the live funding rates across Hyperliquid, dYdX, and Aevo and tell me which venue has the highest annualized APR right now, along with the cross-venue median so I know if it's worth doing at all?”
SOL funding before basis trade
“Before I enter a basis trade on SOL perps, can you check the current 8h funding rate and annualized APR on Hyperliquid, dYdX, and Aevo? I want to see the open interest and mark price too so I can decide which venue to use and whether funding is skewed enough to justify the position.”
Compare ETH perp funding venues
“Which exchange has the lowest funding rate for ETH perps right now? Pull the live data from Hyperliquid, dYdX, and Aevo — I need the per-venue 8h funding and APR side by side so I can figure out where to short and where to go long for the cheapest carry cost.”
Technical details
Endpoint
GEThttps://meryol-payai.hf.space/perps/funding/:market?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a pre-trade cross-venue funding comparison for perpetual futures before opening a carry, delta-neutral, or directional position. It is the right choice when you want a single call to compare funding across Hyperliquid, dYdX, and Aevo simultaneously rather than querying each exchange API individually. Prefer it over single-venue funding endpoints when cross-venue median APR or venue selection for carry trades is relevant.
Side effects
- Unknown or unsupported ticker symbol returns an error or empty venues array
- One or more upstream venues temporarily unavailable — partial results may be returned
- Rate limiting or payment failure (402) if x402 payment header is missing or insufficient
- Stale data if cache has not refreshed within 30s window
