How this service works
Returns live perpetual-futures funding rates, mark and index price, open interest, and 24h volume for BTC, ETH, SOL, XRP, and ADA from Kraken Futures and Hyperliquid, plus a per-symbol consensus with 8h and annualized funding, who pays whom, and a LONG_CROWDED / SHORT_CROWDED / BALANCED crowding label — use it to price carry or spot a crowded side before taking a leveraged position. Cached 5 minutes.
Output
A JSON object keyed by symbol (BTC, ETH, SOL, XRP, ADA), each containing mark price, index price, open interest, 24h volume, per-venue funding rates from Kraken Futures and Hyperliquid, a consensus funding rate with 8h and annualized values, a 'who pays whom' indicator, and a crowding label (LONG_CROWDED / SHORT_CROWDED / BALANCED). Also includes a fetched_at timestamp and any venue_errors. Data is cached for 5 minutes.
Example use cases
Pre-trade carry cost check
“Before I open a long BTC perp position, can you pull the current funding rate, annualized carry cost, and crowding label so I know if longs are already crowded and how much I'd be paying to hold?”
Cross-asset funding rate scan
“Give me the current funding rates and crowding labels for all five coins — BTC, ETH, SOL, XRP, and ADA — across Kraken Futures and Hyperliquid so I can see which perp markets are most expensive or crowded right now.”
Short-side timing signal
“I'm thinking about shorting ETH perps — can you check whether the ETH market is currently SHORT_CROWDED, what the funding rate is, and whether shorts are paying or receiving funding right now?”
Technical details
Endpoint
GEThttps://x402.coinopai.com/api/kronos/futures/funding?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cross-venue consensus view of perpetual futures funding rates, crowding signals, and carry costs for the five major crypto assets (BTC, ETH, SOL, XRP, ADA) in a single call. It is especially valuable before entering or sizing a leveraged position, pricing a carry trade, or detecting one-sided crowding. Prefer it over raw exchange APIs when you want normalized, multi-venue aggregation with pre-computed annualized rates and crowding labels rather than raw tick data.
Side effects
- Venue errors array populated if Kraken Futures or Hyperliquid is unreachable — partial data returned for available venues
- Stale data returned if cache refresh fails — fetched_at timestamp indicates data age
- Invalid symbol query param returns error or falls back to all symbols
- Payment failure (non-2xx from x402 layer) if USDC payment of $0.02 is not properly handled
- Rate limiting or timeouts from upstream venues may produce incomplete open interest or volume fields
