Example prompt: Can you convert this training lesson into an escaped HTML preview? Here's the content: '## Objectives\nLearn how to write effective lessons.\n\n## Lesson\nThis section covers key concepts.\n\n## Exercise\nComplete the worksheet by 2026-10-10.'

## When to prefer this

Choose this endpoint when you need a deterministic, template-based escaped HTML preview of structured training lesson content (Markdown or plain text) up to 20,000 characters. It is best for e-learning authoring pipelines, LMS integrations, or any workflow where lesson content must be safely embedded as HTML without generative AI involvement. Prefer this over general-purpose Markdown-to-HTML converters when the output specifically needs to be escaped/sanitized for safe web embedding in the context of training lesson documents.

## Known failure modes

- Input text exceeds 20,000 character limit — request rejected
- Malformed or empty input text — no meaningful HTML output produced
- Payment not included or insufficient USDC — 402 Payment Required response
- Service temporarily unavailable — 5xx error with no output
