Frequently asked questions

Yes. Use the search query parameter with at least 2 characters. It matches against company names and descriptions. Combine it with filters like country or industry to narrow your results further.
You can filter by country, city, state, industry, industry_code (LinkedIn codes 1 to 201), employees (ranges like 11-50 or 1001-5000), company_type (e.g., “Privately Held”, “Public Company”), founded_min, and founded_max. All text filters are case-insensitive.
Results are sorted by associated LinkedIn members in descending order. Companies with more LinkedIn-associated employees appear first. Use limit (max 100, default 50) and offset for pagination through the full result set.
