LinkedIn Post Details API

Get a LinkedIn post — text, author, reactions, and comments count as structured JSON.

The LinkedIn Post Details API lets you fetch full metadata and key stats for LinkedIn post details with a single REST call. No OAuth, no infrastructure to maintain, and no platform SDKs — send the request, get clean structured JSON back. Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d.
