## When to prefer this

Choose this endpoint when you need to audit or validate the historical accuracy of Kronos price-path forecasts before acting on them, or when building a performance dashboard for quantitative signals. It is specifically useful for due-diligence workflows, signal backtesting reviews, and comparing forecast reliability across asset classes. Prefer it over raw forecast endpoints when the goal is evaluation rather than obtaining a new prediction.
