How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
Returns a JSON object with: cross_sectional_vol (average std of returns across coins per timestamp), correlation_clusters array (2-5 hierarchical groups with avg intra-cluster correlation), diffusion_index_7d and diffusion_index_30d (percentage of coins with positive returns over those windows), advance-decline ratio, new highs/lows percentages, plus _meta, period, and universe fields. Covers 7d, 30d, or 90d periods.
Example use cases
Example prompt
“Can you pull the crypto market dispersion metrics for the last 30 days — I want to see the cross-sectional volatility, how coins cluster by correlation, and what the diffusion index looks like for 7-day and 30-day returns?”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/dispersionWhen to prefer
Use this endpoint when you need market-wide breadth and dispersion analytics across many cryptocurrencies simultaneously — not individual coin data. Ideal for assessing whether a market move is broad-based or concentrated, studying correlation regime shifts, or measuring overall crypto market health over 7d/30d/90d horizons. Prefer this over individual coin price endpoints when the research question involves cross-sectional statistics.
Side effects
- Invalid or unsupported period parameter returns an error
- Service unavailable if underlying price data feed is stale or offline
- Rate limiting or payment failure returns 402 if x402 payment is not processed
- Empty or malformed response if coin universe data is temporarily unavailable
