# Lemmy Post Detail API Documentation

<p><strong>Lemmy Post Detail API</strong> returns a single Lemmy post by its numeric id as JSON: id, title, url, body (markdown plus plain-text), community, creator, score, upvotes, downvotes, comment count, publish date, thumbnail, cross-posts and moderators. The response also includes the comment tree rebuilt from the dotted path, with content (markdown plus plain-text), score, child count and creator per comment. Comments are best-effort within the same billable request.</p>
