How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
A JSON object containing: the current volatility regime label (e.g. 'normal', 'expanded', 'compressed'), next-state transition probabilities for each regime, vol clustering autocorrelation values (ACF array), current annualized volatility as a decimal, and the volatility percentile rank versus historical lookback. Also includes a disclaimer that data is informational only.
Example use cases
ETH options positioning volatility check
“Before I write covered calls on my ETH position, can you tell me what volatility regime we're in right now and how likely it is to stay there or shift — I want to know if I'm selling into expanding or compressing vol?”
Risk management regime alert review
“I'm running an ETH book and need to know whether we're in an elevated vol regime or not, what percentile today's annualized volatility is sitting at historically, and how clustered the recent vol has been so I can size my risk limits appropriately.”
Systematic trading signal generation
“Pull the current ETH volatility regime classification along with the transition probabilities to each next state — I'm feeding this into my systematic strategy to decide whether to go long or short volatility this week.”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/vol-regime/ETHWhen to prefer
Use this endpoint when you need Ethereum-specific volatility regime classification with probabilistic next-state forecasting, especially for risk management, options positioning, or systematic trading signal generation. Prefer this over generic price endpoints when you specifically need vol regime context (normal/expanded/compressed) and transition probabilities rather than just a price quote.
Side effects

- Network timeout if market data feed is unavailable

- Stale data if upstream price feed is delayed
- Rate limiting if too many calls made in short succession
