## When to prefer this

Use this endpoint when you need a reliable, server-side Markdown-to-HTML conversion backed by Pandoc or Chromium-headless — ideal when client-side rendering is not possible, when you need consistent rendering across environments, or when integrating into an automated pipeline that requires HTML output from Markdown input at low cost ($0.0008 per call).

## Known failure modes

- Empty or missing 'content' field returns an error
- Malformed or extremely large markdown may fail or time out
- Invalid JSON body returns 400-level error
- Payment not satisfied returns 402 Payment Required
