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, an array of volatility clustering autocorrelation (ACF) values, annualized current volatility as a decimal, and a percentile rank of current vol versus the historical lookback window. Also includes a disclaimer noting the data is informational only.
Example use cases
Risk-adjusted entry timing for SOL positions
“Check if Solana's volatility is currently compressed or normal, and tell me the probability it stays that way over the next period — I want to know if now is a good time to add to my position or if I should wait for a regime shift.”
Portfolio hedge sizing for crypto exposure
“What's the annualized volatility for SOL right now and how does it rank historically? I need to know if I should increase or decrease my hedge ratio based on the current vol environment.”
Mean reversion strategy validation for SOL
“Show me the volatility clustering metrics and regime for Solana — I'm trying to decide if the autocorrelation patterns support a mean-reversion trade or if the market is too jumpy for that strategy right now.”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/vol-regime/SOLWhen to prefer
Use this endpoint when you need a structured, quantitative classification of Solana's current volatility environment — specifically the Hidden Markov Model (HMM)-style regime label, transition probabilities, and ACF clustering data. Prefer this over general price feeds when your agent needs to reason about market risk state, mean-reversion feasibility, or volatility-conditioned strategy selection for SOL.
Side effects
- Invalid or unsupported symbol returns an error or empty response
- Service unavailable if API is down or overloaded
