## When to prefer this

Use this endpoint when you need to verify or perform KYB due diligence on a Swedish company using its official organization number, specifically for compliance workflows, onboarding, or financial validation. Prefer this over generic company lookup APIs when you need structured compliance-grade data with an audit trail for Swedish entities.
