How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
A JSON object containing: current annualized conditional volatility, short-term volatility forecasts at 1d/7d/30d horizons, fitted GARCH parameters (omega, alpha_1, beta_1, persistence), and the estimated half-life in days for volatility to mean-revert. Includes a research disclaimer.
Example use cases
Example prompt
“What's Ethereum's current GARCH volatility forecast — I want the annualized conditional vol right now, the 1-day, 7-day, and 30-day forecasts, the persistence level, and how many days until volatility reverts to its mean?”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/garch/ETHWhen to prefer
Use this endpoint when you need quantitative, model-based volatility estimates for ETH specifically — especially when you need GARCH parameters, persistence metrics, or a half-life for mean-reversion timing. Prefer this over simple price endpoints when your use case involves risk modeling, options pricing intuition, or assessing whether current volatility is elevated relative to long-run levels.
Side effects
- Invalid or unsupported symbol returns an error
- Payment not included or insufficient (x402 payment required, $0.05 USDC)
- Service temporarily unavailable or model not yet computed for current period
- Rate limit exceeded for repeated rapid calls
