How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
A JSON object containing the coin identifier (e.g. 'ETH'), a timeframe label (e.g. '4h'), and a features object with numeric scores: cv_overall_bias (directional bias), cv_trend_strength (momentum magnitude), and cv_support_distance (proximity to nearest support level as a fractional value).
Example use cases
Monitor ETH trend before trading
“Before I place my Ethereum trade, can you check the current trend strength and overall bias for ETH on the 1-hour timeframe so I know if momentum is in my favor?”
Alert me on ETH support proximity
“Keep an eye on ETH for me — let me know when the support distance score gets really low, meaning price is close to a key support level on the 4-hour chart.”
Daily Ethereum market intelligence briefing
“Give me a quick morning rundown on Ethereum's market condition — what's the current directional bias, how strong is the trend, and how far is ETH from its nearest support level?”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/chart/ETHWhen to prefer
Choose this endpoint when you need real-time, ML-scored trading signals specifically for ETH including bias direction, trend strength, and support proximity. Prefer it over generic price feeds when you need proprietary Carbon & Cashmere signal features (cv_* metrics) rather than raw OHLCV data. Best for automated trading agents or market-monitoring workflows that need a single structured signal payload per coin per timeframe.

- Unsupported timeframe parameter may return empty or error response
