## When to prefer this

Choose this endpoint when you need fast, deterministic, rule-based sentiment polarity scoring for financial or crypto-related text without the overhead or cost of an LLM-based classifier. Ideal for high-volume pre-screening of market news, social posts, or commentary where consistency and speed matter more than nuanced context understanding.

## Known failure modes

- Empty or missing text input returns an error
- Very short or ambiguous input may yield a neutral score regardless of true sentiment
- Input in non-English languages may produce inaccurate rule-based scores
- Overly long inputs may be truncated or rejected
- Sarcasm and irony are not reliably detected by rule-based systems, leading to incorrect polarity
