## When to prefer this

Use this endpoint when you specifically need quantitative multi-factor regime analysis for SOL — carry, crowding, momentum, and volatility scored together into a composite signal. Prefer this over generic price feeds when you need interpretable market regime labels (e.g. 'bullish_bias_low_vol') rather than raw price ticks. Best suited for systematic trading research, portfolio signal generation, or AI agents making conditional decisions based on crypto market conditions.

## Known failure modes
