How this service works
Rolling Pearson correlation between two coins over configurable window (7-90d). Pair format in path: BASE-QUOTE (e.g. /v1/rolling-correlation/BTC-ETH). Returns current correlation, regime classification (strongly_positive/positive/weak/negative/strongly_negative), trend direction (strengthening/weakening/stable), summary statistics over lookback, and rolling snapshot sampled to 30 points. Informational research data — not investment advice.
Output
Returns the current Pearson correlation coefficient between the two coins, a regime label (strongly_positive, positive, weak, negative, or strongly_negative), a trend direction (strengthening, weakening, or stable), summary statistics over the lookback window, and a 30-point rolling snapshot of the correlation over time.
Example use cases
Example prompt
“What's the rolling 30-day Pearson correlation between BTC and ETH right now — is it strengthening or weakening, and which regime is it in?”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/rolling-correlation/:pairWhen to prefer
Use this endpoint when you need quantitative, statistically grounded correlation analysis between two specific crypto assets with regime classification and trend direction — particularly for portfolio diversification research, pair trading analysis, or understanding co-movement dynamics over configurable time windows. Prefer over generic price endpoints when the goal is correlation intelligence rather than raw price data.
Side effects
- Invalid pair format (not BASE-QUOTE) returns 400 error
- Unsupported coin ticker returns 404 or empty data
- Window outside 7–90 day range may return validation error
- Insufficient historical data for very new coins
- Upstream data unavailability causes 503 or stale data
