## When to prefer this

Choose this endpoint when you need a fast, deterministic heading outline from a product specification document without any AI-generated prose or creative rewriting. It is ideal for document structure validation, TOC generation, and pre-writing organization where reproducibility and consistency matter. Prefer this over generative tools when you want the same input to always produce the same outline.

## Known failure modes

- Input text exceeds 20,000 character limit — request rejected
- Empty or missing text field — no outline produced
- Input contains no recognizable headings — empty or minimal outline returned
- Malformed Markdown with inconsistent heading syntax — partial outline
