Example prompt: Can you run a length and paragraph profile on this case study text I wrote — it covers our client challenge, solution, and results sections — and tell me the word count, character count, and paragraph breakdown?

## When to prefer this

Choose this endpoint when you need a deterministic, reproducible length and paragraph profile specifically for a case study document (Markdown or plain text up to 20,000 characters). It is ideal for editorial workflows, content audits, and formatting checks where consistent measurement is required without any generative AI output or fact-checking.

## Known failure modes

- Input text exceeds 20,000 character limit — request will be rejected or truncated
- Empty or missing text field returns an error or empty profile
- Non-text binary content passed as input may cause parsing failures
- Malformed Markdown may affect paragraph detection accuracy
