## Convert markdown to HTML
- [PUT /api/v1/markdown](https://docs.wellesley.social/openapi/markdown/paths/~1api~1v1~1markdown/put.md): Converts markdown formatted text to HTML for preview purposes. By default, processes hashtags into linked tags, @mentions into profile links, and custom emoji shortcodes into images. Use ?skipAutolink=true to get a plain markdown-to-HTML conversion without autolinking. Requires authentication.
