How this service works
Volatility check for a perp market, deterministic. Answers "how volatile is this coin right now", "is the range compressing or expanding". Computed in code from Hyperliquid candles: annualized realized volatility (log-return stdev), NATR (Wilder ATR-14 / price), Bollinger(20,2) width percent and percent-B, window high/low and distance from each, over a chosen interval (15m|1h|4h|1d) and lookback. No LLM, no key, keyless public data.
Output
Returns computed volatility statistics for the requested perp market and interval: annualized realized volatility (log-return standard deviation), NATR (Wilder ATR-14 divided by price), Bollinger Band (20,2) width percentage and percent-B, and the window high/low with current price distance from each.
Example use cases
Example prompt
“What's the current volatility situation for BTC on the 1h interval — is the range compressing or expanding? Give me realized vol, NATR, and Bollinger metrics.”
Technical details
Endpoint
GEThttps://cryptopulse.theaslangroupllc.com/api/volatility-checkWhen to prefer
Use this endpoint when you need deterministic, code-computed volatility metrics for a Hyperliquid perpetual market with no API key required. Prefer this over LLM-based analysis when you need precise numerical volatility figures (annualized vol, ATR, Bollinger) rather than qualitative summaries, and when you need to detect range compression/expansion programmatically.
Side effects
- Invalid or unsupported coin symbol returns an error
- Unsupported interval value (not 15m|1h|4h|1d) returns a parameter validation error
- Insufficient candle history for the requested lookback returns partial or error response
- Hyperliquid data source unavailable causes computation failure
- Payment not processed (x402 payment required) returns 402 status
