How It Works

Takes one or more LinkedIn post URLs
Calls the harvestapi~linkedin-post-comments Apify actor (no cookies needed)
Extracts commenter name, headline (title + company), LinkedIn profile URL, and comment text
Parses headline into separate title and company fields where possible
Optionally deduplicates across multiple posts by LinkedIn profile URL
