Example prompt: Can you run a KYB check on the Portuguese company 'Sonae SGPS' — I need their official registration details and compliance status from the Portuguese registry?

## When to prefer this

Use this endpoint when you need official Portuguese company data for KYB, due diligence, or compliance checks on businesses registered in Portugal. Prefer over generic web search when you need structured, auditable registry data. Complements the sibling Dutch KVK endpoint when doing multi-country European KYB workflows.
