How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
A JSON object containing the current correlation coefficient between BTC and SOL, a regime label (e.g. 'strongly_positive'), a trend label (e.g. 'stable'), the historical percentile of the current correlation, mean and standard deviation over the lookback period, the number of data points, and the window/lookback configuration used.
Example use cases
BTC-SOL diversification portfolio check
“I'm rebalancing my crypto portfolio and want to know if BTC and SOL are still moving in lockstep or if there's any real diversification benefit right now — what does the current correlation regime and trend say?”
Detect BTC-SOL divergence signal
“Has the correlation between BTC and SOL started breaking down recently? I want to know if we're leaving a strongly positive regime and whether today's reading is historically low compared to the past 90 days.”
Pair trade correlation timing
“I'm considering a BTC/SOL pair trade and need to know if their rolling correlation is at an extreme percentile historically — is it unusually high or low right now, and has it been stable or trending in one direction?”

Use this endpoint when you need a quantitative measure of how synchronized BTC and SOL price movements are over a rolling window, including regime classification and percentile context. Prefer this over generic price endpoints when you need correlation-based portfolio or diversification analysis, or when you want to know whether two assets are trending together or diverging.
