How this service works
Perp funding-rate HISTORY, deterministic and lookahead-safe. Answers "what was funding for this coin over the last N days", "backtest my strategy against real funding". Hourly Hyperliquid funding rows for up to 90 days per call (windows anchor anywhere in a year+ of history): settlement time, hourly rate, annualized percent, premium, and an available_at timestamp per row so recorded history is point-in-time honest. Summary stats included. Keyless public data, no LLM.
Output
An array of hourly funding rate rows for the requested coin and date window, each containing: settlement timestamp, hourly funding rate, annualized funding rate percentage, premium, and an available_at timestamp (enabling point-in-time honest backtesting). Also includes summary statistics over the requested period such as average, min, and max rates.
Example use cases
Example prompt
“Pull the hourly Hyperliquid funding rate history for BTC over the last 60 days — I need the settlement time, hourly rate, annualized percent, premium, and available_at per row so I can backtest a funding arbitrage strategy without lookahead bias.”
Technical details
Endpoint
GEThttps://cryptopulse.theaslangroupllc.com/api/funding-history?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need point-in-time honest historical funding rate data for perpetual futures on Hyperliquid — especially for backtesting trading strategies, auditing past funding payments, or analyzing funding rate trends over days to months. Prefer this over a real-time funding endpoint when you need historical windows rather than current rates, and over generic crypto data APIs when you specifically need Hyperliquid perp funding with lookahead-safe available_at timestamps.
Side effects
- Unknown or unsupported coin symbol returns an error or empty dataset
- Requested date range exceeds 90-day maximum window per call
- Future dates or dates beyond the available history (~1 year) return no data
- Malformed date/time parameters cause a 400 bad request
- Network or upstream Hyperliquid data unavailability causes a 503 or timeout
- Payment not processed correctly results in a 402 response
