Example prompt: Can you extract the Architecture section from my technical design document? Here's the full Markdown text: ## Architecture
We use a microservices approach with three primary services...
## Interfaces
Public REST API exposed on port 443...

## When to prefer this

Choose this endpoint when you need to deterministically extract a named section from a technical design document in Markdown or plain text format without any generative processing or hallucination risk. Ideal for pipeline steps where a specific section (e.g. Architecture, Interfaces, Trade-offs) must be isolated from a larger document for downstream processing, review, or storage. Prefer this over general-purpose LLM extraction when reproducibility and bounded output are required.

## Known failure modes

- Input text exceeds 20,000 character limit — request rejected
- Section header not found in the supplied document — empty or no result returned
- Malformed Markdown with ambiguous section boundaries — incorrect section may be extracted
- Non-technical-design document supplied — section patterns may not match expected templates
