Choose this endpoint when you need a lightweight, per-call sentiment label plus emotion keyword extraction for short-to-medium text snippets at low cost ($0.001/call). It is ideal for real-time pipelines, review moderation, and triage workflows where speed matters and you need both a polarity label and keyword-level emotion signals in one call.

## Known failure modes

- Empty string input may return ambiguous or default classification
