How this service works
Perpetual funding rates on Hyperliquid, dYdX, Paradex and Aevo normalized to 1h, 8h and annualized APR. For one coin it compares venues and the long/short spread; without a coin it lists the biggest cross-exchange funding spreads (funding arbitrage).
Output
Returns a list of exchanges with their current funding rates for the requested coin (1h %, 8h %, annualized APR %, price, open interest in USD), plus a strategy note and the annualized spread between the highest and lowest venues. When no coin is specified, returns a ranked list of coins with the largest cross-exchange funding spreads for arbitrage identification.
Example use cases
Funding arbitrage scanner across venues
“Scan for the biggest cross-exchange funding rate spreads right now across Hyperliquid, dYdX, Paradex, and Aevo — show me the top 10 coins with the widest funding arbitrage opportunities.”
ETH funding rate venue comparison
“What are the current perpetual funding rates for ETH on all supported exchanges? I want to see the 1h, 8h, and annualized APR for each venue and understand which side (long or short) is getting paid.”
SOL funding cost before opening position
“Before I open a long on SOL perps, can you check the funding rates across Hyperliquid, dYdX, and Aevo and tell me which exchange has the cheapest funding cost right now in annualized terms?”

Endpoint
POSThttps://api.vextorium.com/funding-comparar-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, normalized perpetual funding rate comparisons across Hyperliquid, dYdX, Paradex, and Aevo in a single call. It is ideal for funding arbitrage discovery (delta-neutral carry trades), pre-trade cost analysis (which venue is cheapest to hold a position), or monitoring funding rate divergence across major perp venues. Prefer this over manually querying individual exchange APIs when you need cross-venue normalization to a common time base (1h/8h/APR).
Side effects
- Coin symbol not found on any supported exchange — returns empty or null exchange list
- Exchange API temporarily unavailable — partial results with missing venue data
- Invalid coin ticker format — malformed input leads to empty response
- Rate data stale if upstream exchange feeds lag — timestamps may reflect slightly delayed rates
