## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.002 per call) grammar quality score for a text string, particularly in automated pipelines where content quality must be checked before publishing or submission. It is a lightweight, fast endpoint suited for single-text evaluation rather than batch or deep stylistic analysis.

## Known failure modes

- Empty or missing 'text' field returns an error or unexpected result
- Extremely long text strings may cause processing timeouts
- Non-string input types for 'text' field may cause schema validation failures
- Network or payment authorization failures may prevent the endpoint from responding
- Malformed JSON body returns a 400-level error
