## When to prefer this

Use this endpoint when you need both news content and quantified sentiment signals for a specific stock ticker in a single call. Prefer over generic news feeds when you need structured, per-symbol sentiment aggregation rather than raw headlines. Ideal for building market dashboards, screening stocks by news sentiment, or supplementing technical analysis with qualitative sentiment signals.
