Example prompt: Can you calculate the Smog Index readability score for this paragraph: 'Effective automation requires systematic planning, iterative refinement, and disciplined execution across multiple operational domains.'?

## When to prefer this

Choose this endpoint when you specifically need the Smog Index readability formula (Robert McLaughlin, 1969) rather than other readability metrics like Flesch-Kincaid or Gunning Fog. It is best suited for assessing medical, legal, or technical text complexity. At $0.002 per call it is cost-effective for single-document checks or light batch workflows where per-unit cost matters.

## Known failure modes

- Empty or missing text field returns error or unexpected result
- Text too short for reliable Smog Index calculation (formula requires sufficient polysyllabic words)
- Non-English text may produce inaccurate or meaningless scores
- Malformed JSON request body causes processing failure
- Very long texts may exceed input limits
