How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
A JSON object containing: GARCH(1,1) model parameters (omega, alpha_1, beta_1), persistence (alpha+beta), annualized conditional volatility now (~42%), multi-horizon volatility forecasts for 1d/7d/30d, and the volatility half-life in days. Includes an informational disclaimer.
Example use cases
Bitcoin options pricing volatility input
“I'm pricing some Bitcoin options and need a model-driven volatility estimate — pull the current GARCH annualized conditional vol and the 30-day forward forecast so I can use it as my vol input.”
Detect Bitcoin volatility regime shift
“Is Bitcoin in a high-persistence volatility regime right now? Give me the GARCH alpha and beta parameters and the half-life so I can tell whether the current vol is likely to stick around or mean-revert quickly.”
BTC risk management weekly review
“For my weekly crypto risk review, give me Bitcoin's current annualized conditional volatility and the 1-day, 7-day, and 30-day GARCH forecasts so I can assess whether to adjust my position sizing.”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/garch/BTCWhen to prefer
Use this endpoint when you need a quantitative, model-driven volatility estimate for Bitcoin specifically — particularly for risk management, options pricing context, or regime detection where GARCH persistence and half-life matter. Prefer over simple realized-vol lookups when you need forward-looking multi-horizon forecasts and model parameters.
