Ideal for agents automating content QA pipelines, checking individual documents for SEO optimization, or validating that keyword usage falls within acceptable ranges before publishing.

## Known failure modes

- Missing 'text' or 'keyword' field returns an error response
- Empty string inputs may return a zero-density result or error
- Very large text bodies may time out or be truncated
- Non-string types in schema fields cause validation failure
