## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.002 per call) readability grade for a piece of text, particularly for content in the AI, side hustle, or digital income space. Prefer it when you want a simple pass/fail or numeric readability signal without needing a full NLP pipeline. If you need deep linguistic analysis, sentiment, or entity extraction, consider a more comprehensive NLP API instead.

## Known failure modes

- Extremely short text may produce unreliable or low-confidence grades
- Very long texts may time out or be truncated
