## When to prefer this

Choose this endpoint when you specifically need the Automated Readability Index metric — a formula-based grade-level readability score derived from character counts, word counts, and sentence counts. Prefer it over general NLP APIs when you want a fast, deterministic, interpretable readability score without ML overhead, especially for English-language content quality checks, educational material assessment, or audience-fit validation.

## Known failure modes

- Empty or missing text field returns an error or zero score
- Extremely short text (fewer than 2-3 sentences) may yield unreliable or edge-case ARI values
- Non-English text may produce inaccurate scores since ARI is calibrated for English
- Malformed JSON request body causes a 400-level error
- Very large text payloads may be rejected or time out
