Example prompt: Can you go through this case study draft and give me a complete inventory of every quoted passage in it? Here's the text: [paste Markdown or plain text up to 20,000 characters].

## When to prefer this

Choose this endpoint when you need a deterministic, bounded extraction of quoted passages specifically from a case study document. It is ideal when you require a consistent, repeatable inventory without generative AI embellishment — suitable for editorial audits, attribution checks, or compliance reviews. Prefer this over general-purpose LLM summarization when you need reliable, non-hallucinated extraction of only what is explicitly quoted in the source text.

## Known failure modes

- Input text exceeds 20,000 character limit — request will be rejected or truncated
- No quoted passages found in the document — inventory will be empty
- Malformed or ambiguous quotation formatting may cause some quotes to be missed
- Non-case-study documents submitted may yield unexpected or sparse results
