## Accessing content as Markdown

Most documentation pages, FAQ items, and blog posts can be retrieved as lean Markdown. There are two ways to request this:

- **`.md` suffix**: Append `.md` to any supported URL (e.g. `https://ohdear.app/docs/features/uptime-monitoring.md`)
- **`Accept` header**: Send `Accept: text/markdown` in your HTTP request to get the Markdown version of the same URL

Both approaches return the same lightweight Markdown content, optimized for LLM consumption.
