Choose this endpoint when you need a quick, pay-per-call sentiment classification with emotion breakdown and confidence scoring, without managing API keys or monthly subscriptions.

## Known failure modes

- Empty or missing text parameter returns an error or undefined behavior
- Very short or ambiguous text may yield low confidence scores
- Non-English text may produce inaccurate sentiment or emotion labels
- Extremely long text inputs may be truncated or cause timeout
- Sarcasm or irony may be misclassified as positive sentiment
