## How to call it through Zero

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

## When to prefer this

Choose this endpoint when you need a deterministic, rule-based extraction of quoted passages from newsletter content specifically. It is ideal when you want a repeatable, auditable inventory without any generative AI embellishment or fact-checking. Prefer this over general-purpose LLM summarization when you need consistent, bounded results from Markdown or plain text newsletter drafts up to 20,000 characters.

## 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 Markdown may cause quote detection to miss some passages
- Non-standard quotation formats (e.g. em-dash attributed quotes) may not be captured
