BTC Coin Days Destroyed (CDD) — 24h History is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).
Retrieves the last 24 hours of Bitcoin Coin Days Destroyed (CDD) data, measuring age-weighted coin movement to detect smart money activity and long-term holder behavior.
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Returns an array of BTC Coin Days Destroyed values over the past 24 hours, representing the age-weighted volume of moved coins. High CDD values signal long-term holders (HODLers) are selling, while low values suggest dormant coins remain unmoved — useful for identifying potential market tops or bottoms.
GEThttps://api.carbon-cashmere.de/v1/onchain/cddUse this endpoint when you need Bitcoin-specific age-weighted on-chain movement data (CDD) rather than raw transaction volume or price data. Ideal for smart money analysis, HODLer behavior tracking, and identifying potential market cycle inflection points. Prefer over generic price or volume endpoints when the user wants to understand whether long-term BTC holders are distributing coins.
