Example prompt: Can you audit the heading hierarchy of my process guide document — here's the markdown content — and tell me if the headings are nested correctly and flag any structural issues?

## When to prefer this

Choose this endpoint when you need a deterministic, low-cost ($0.01 USDC) structural audit of heading hierarchy specifically in process guide documents formatted as Markdown or plain text. Prefer this over general-purpose LLM document review when you want a repeatable, template-driven output rather than generative prose feedback.

## Known failure modes

- Input text exceeds 20,000 character limit — request will be rejected or truncated
- Empty or missing text field — no audit can be performed
- Input contains no headings — audit returns empty or trivial result
- Non-Markdown or ambiguous formatting may reduce audit accuracy
- Payment failure (x402) prevents endpoint access
