## When to prefer this

Choose this endpoint when you need fast lexicon-based sentiment scoring over transcript segments for a specific topic — especially within the Monexus model-economy and AI-capex domain. Prefer it over general NLP APIs when you need sentiment grounded in financial/tech transcript content rather than social media or reviews, and when you want both relevance-ranked retrieval and sentiment in one call.
