## Known failure modes

- Missing required 'text' field returns an error response
- Very short or empty text may yield fewer keywords than requested
- Ambiguous or highly technical content may produce low-relevance keywords
- Count parameter exceeding the meaningful keyword density of the text may return fewer results than specified
