## When to prefer this

Choose this endpoint when you need finance-specific sentiment analysis on market news, earnings reports, press releases, or ticker-related commentary. It is purpose-built for financial NLP rather than generic sentiment, making it more appropriate than general-purpose text classifiers when domain context (stocks, markets, macro events) matters.
