How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
A JSON object containing: the current vol regime label (e.g. 'normal'), transition probabilities to each next state (normal/expanded/compressed), an ACF array for vol clustering at multiple lags, the current annualized volatility as a decimal, and a percentile rank of current vol vs the historical lookback window.
Example use cases
Options strategy vol environment check
“Before I set up a BTC options position, can you tell me what volatility regime Bitcoin is currently in and how likely it is to shift to an expanded or compressed state soon? I want to make sure I'm sizing my position appropriately for the environment.”
Risk sizing for BTC trend system
“I'm running a trend-following system on Bitcoin and need to know whether we're in a compressed or expanded vol regime right now, plus where current annualized vol ranks historically — I adjust my position size based on the vol environment.”
Detect incoming Bitcoin vol regime shift
“Is Bitcoin volatility showing any signs of a regime shift right now? Give me the current state, the transition probabilities into an expanded regime, and whether the vol clustering stats suggest momentum or mean-reversion in volatility.”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/vol-regime/BTCWhen to prefer
Use this endpoint when you need a probabilistic, regime-aware view of Bitcoin's volatility state — particularly useful for options strategies, risk sizing, or trend-following systems that need to adapt to vol environment. Prefer this over simple realized-vol endpoints when you need forward-looking regime transition probabilities and ACF clustering diagnostics.
Side effects
- Invalid or unsupported symbol returns 404 or empty result
- Network timeout if upstream market data feed is delayed
- Malformed response if vol model has insufficient recent data
- Payment failure (x402) if USDC balance is insufficient for the $0.01 fee
- Rate limiting if too many requests are made in quick succession
