## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.002) programmatic Gunning Fog Index score for a piece of text, especially within an automated content pipeline or agent workflow. It is well-suited for checking readability of blog posts, marketing copy, educational material, or any written content where audience comprehension level matters. Prefer it over general-purpose NLP APIs when the specific Fog Index metric is required rather than general sentiment or grade-level estimates.

## Known failure modes

- Empty or missing 'text' field returns an error or zero score
- Extremely short text (fewer than 2 sentences) may produce unreliable scores
- Non-English text may yield inaccurate results since the algorithm is designed for English
- Very long texts may time out or be truncated
- Malformed JSON request body returns a 400-style error
