## When to prefer this

Choose this endpoint when you need fast, pay-per-call AI-powered keyword extraction from arbitrary text without setting up your own NLP pipeline. Ideal for SEO workflows, content tagging, document indexing, or any scenario where you need to identify the most salient terms from a block of text. Best when you need a lightweight, on-demand solution rather than a bulk batch processor.

## Known failure modes

- Missing required 'text' field returns an error response
- Empty string input may return empty keywords or an error
- Very short text may yield few or no meaningful keywords
- Invalid 'count' type (non-integer) may cause a validation error
- Network or server errors on the Vercel deployment may return 5xx responses
