How this service works
Perp funding-rate check, deterministic. Answers "what is the funding rate for this coin right now", "am I paying or earning to hold this perp", "which venue has the best funding". One coin (or top markets by open interest): hourly funding, 8h-equivalent, annualized percent, open interest, mark price, premium — plus predicted funding across venues normalized to a comparable 24h rate. Keyless Hyperliquid public data. No LLM.
Output
Returns hourly funding rate, 8-hour equivalent, annualized percentage, open interest, mark price, and funding premium for the requested coin's perpetual market, plus predicted funding rates across venues normalized to a 24-hour comparable rate — all sourced deterministically from Hyperliquid public data with no LLM inference.
Example use cases
Example prompt
“What's the current funding rate for ETH perp right now — hourly and annualized — and which venue has the best rate if I want to hold a long?”
Technical details
Endpoint
GEThttps://cryptopulse.theaslangroupllc.com/api/funding-checkWhen to prefer
Use this endpoint when you need deterministic, real-time perpetual funding rate data for a specific coin, particularly when comparing venues or deciding whether to hold, open, or close a perp position. Prefer this over general market data APIs when funding rate specifics (hourly, 8h, annualized, predicted) and open interest context are needed together in one call. Best for trading agents, portfolio monitors, and arbitrage detectors operating on Hyperliquid data.
Side effects
- Unsupported or unrecognized coin symbol returns an error or empty result
- Hyperliquid public API unavailability causes data fetch failure
- Invalid request parameters return a 400-level error
- Payment not received or insufficient USDC triggers x402 payment required response
