When to prefer

Choose this endpoint when you need narrative-level crypto intelligence derived from news — e.g., understanding which storylines (regulation, ETF, DeFi, AI) are gaining or fading momentum and which coins are associated with them. Prefer over raw price feeds or ML signal endpoints when the goal is qualitative theme detection, news-based alpha generation, or narrative-driven trading context.
