hyperliquid_get_funding_rates

Use this when you need current funding rates across all Hyperliquid perpetual markets. Returns real-time funding rate, premium, open interest, and mark price for every listed perp coin on Hyperliquid DEX, sorted by your chosen criteria.

Parameters

NameTypeRequiredDescription
sortstringnoSort order for funding rates. 'highest' = most positive first (shorts pay longs), 'lowest' = most negative first (longs pay shorts), 'abs' = highest absolute value first (default).

Example response:

{ totalMarkets: 229, sort: "abs", rates: [{ coin: "BTC", fundingRate: 0.000125, annualizedRate: 13.69, premium: 0.0002, openInterest: 1250000000, markPrice: 68500.5 }, ...] }

When to use: opening perp positions to check funding cost. Essential for carry trade analysis, market sentiment gauging, and identifying crowded trades.

Not for: historical funding data (use hyperliquid_get_funding_history), vault performance data (use hyperliquid_get_vault_details), whale position tracking (use hyperliquid_track_whale_positions).

hyperliquid_get_funding_history

Use this when you need historical funding rate data for a specific Hyperliquid perpetual market. Returns timestamped funding rate entries over a configurable lookback window, plus summary statistics including average, min, max, and standard deviation.

Parameters

NameTypeRequiredDescription
coinstringyesCoin ticker symbol (e.g. BTC, ETH, SOL, DOGE). Must match a Hyperliquid perp market.
hoursnumbernoLookback window in hours. Default: 24. Max: 720 (30 days). Each funding period is 8 hours, so 24h returns ~3 entries.

Example response:

{ coin: "ETH", hours: 24, entries: [{ time: "2026-04-13T08:00:00Z", fundingRate: 0.0001, annualizedRate: 10.95 }, ...], summary: { count: 3, avgRate: 0.00012, avgAnnualized: 13.14, minRate: 0.00008, maxRate: 0.00015, stdDev: 0.000029 } }

Not for: current rates across all markets (use hyperliquid_get_funding_rates), CEX funding rates (use funding_rates_get_current).

hyperliquid_find_funding_arb

Use this when you need to find funding rate arbitrage opportunities on Hyperliquid. Scans all 229 perp markets and returns coins where the absolute funding rate exceeds 0.01% per 8h period (annualized > 36%), flagged as long or short opportunities based on rate direction.

Parameters

NameTypeRequiredDescription
thresholdnumbernoMinimum absolute funding rate to qualify as an arb opportunity. Default: 0.0001 (0.01% per 8h, ~36% annualized). Lower values return more results.

Example response:

{ threshold: 0.0001, totalOpportunities: 12, longOpportunities: 5, shortOpportunities: 7, opportunities: [{ coin: "PEPE", fundingRate: 0.0005, annualizedRate: 54.75, direction: "short opportunity", openInterest: 85000000, markPrice: 0.0000125, premium: 0.001 }, ...] }
