Example prompt: Can you calculate the Smog Index for this article text: 'Artificial intelligence systems leverage sophisticated algorithmic architectures to process multidimensional datasets, enabling consequential inferences across heterogeneous domains...'? I want to know how readable it is.

## When to prefer this

Use this endpoint when you need a quick, affordable readability score specifically using the Smog Index formula — ideal for content creators, educators, or marketers who want to gauge text complexity. Prefer this over general-purpose NLP APIs when you specifically need grade-level readability metrics rather than sentiment, classification, or summarization.

## Known failure modes

- Empty or missing text field returns an error
- Text too short for reliable Smog Index calculation (requires polysyllabic word sampling)
- Non-text or binary input causes processing failure
- Very long text may time out or return partial results
- Non-English text may produce inaccurate or meaningless scores
