Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/features/:var1When to prefer
Choose this endpoint when you need a pre-computed, ready-to-use ML feature vector for a single cryptocurrency combining multiple signal categories (technical, sentiment, microstructure, derivatives) into one call. Ideal for feature engineering pipelines, custom ML model inference, and quantitative crypto research where you want a curated set of 34 standardized features rather than assembling them from multiple data sources yourself.
Side effects
- Unsupported coin ticker returns 400 or 422 — only 34 specific tickers are supported (BTC, ETH, SOL, etc.)
- Payment failure (x402) if USDC not provided — endpoint costs $0.01 USDC per call
- Upstream data unavailability for options or orderbook features may return partial or null values
- Rate limiting if too many requests are made in short succession
- Network timeout if upstream data sources are slow to respond
