## When to prefer this

Choose this endpoint when you need a deterministic, rule-based audit of heading hierarchy specifically within support article documents. It is ideal for CI/CD documentation pipelines, help center QA workflows, or content governance checks where generative AI output is not needed and consistency is paramount. Prefer this over general-purpose LLM document review when you need reproducible, bounded results at low cost ($0.01 per call).
