How this service works
Live perpetual-futures funding rates per market — each market's funding rate as hourly, the standard 8-hour figure and annualized %, alongside mark price and open interest. Ranked by the most extreme (|annualized|) funding by default; pass `coins` to get the funding rate for a specific market (e.g. ["BTC","ETH"]). Real-time crypto perp funding rate feed. Data source: Hyperliquid (dYdX fallback).
Output
Returns a ranked list of perpetual futures markets with per-market funding data including coin symbol, hourly funding rate, annualized funding rate, and absolute funding magnitude used for ranking. Results are sorted by highest absolute annualized funding by default, covering up to 250 markets or filtered to specified symbols.
Example use cases
Spot extreme funding for mean-reversion trade
“Which perp markets have the most extreme funding rates right now — positive or negative? Give me the top 15 ranked by absolute annualized funding so I can look for mean-reversion opportunities.”
Monitor BTC and ETH funding sentiment
“What are the current perpetual funding rates for BTC and ETH? I want to know if the market is leaning long or short based on whether funding is positive or negative.”
Screen altcoins for funding arbitrage
“Pull the funding rates for SOL, AVAX, MATIC, ARB, and OP perp markets — I'm looking for any big divergences from zero that might signal a funding rate arbitrage play.”

Endpoint
POSThttps://crypto.openverbs.com/v1/funding?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need live perpetual futures funding rate data across on-chain DEX markets, especially when you want to rank or filter markets by funding intensity. Prefer this over spot price or staking endpoints when your use case is derivatives-specific — identifying funding arbitrage, gauging market sentiment via funding sign, or screening for extreme funding events across a broad set of symbols.
Side effects
- Unknown coin symbol returns empty result or error
- Limit exceeding 250 returns validation error
- Network or upstream DEX data unavailability returns 5xx
- Payment not attached or insufficient returns 402 Payment Required
- Malformed coins array (items too long or too many) returns 400
