Endpoint
GEThttps://api.carbon-cashmere.de/v1/features/BTCWhen to prefer
Choose this endpoint when you need a broad, pre-aggregated set of Bitcoin features — technical indicators, on-chain signals, microstructure, and options data — in a single call, especially for ML model inference, quant research, or building a dashboard. Prefer it over assembling individual data streams when you need a comprehensive feature vector for BTC specifically and want to avoid multiple API round-trips.
