Frequently asked questions

Company data comes from TechnologyChecker’s database of 25.4M LinkedIn company records. Each record includes firmographic details like industry, location, employee count range, founding year, company type, description, and specialties.
The API returns HTTP 404 with error code NOT_FOUND. Not every domain has a matching LinkedIn company record. The database covers 25.4M companies, so smaller or newer businesses might not be included yet. You’re not charged credits for 404 responses.
No. This endpoint returns only company firmographic data. To get a domain’s technology stack, use GET /v1/domain/{domain}. Combine both endpoints to build a complete company profile with tech stack data — that’s 2 credits total.
