🟢lookup_phone_number(number, country, language)
Look up who is behind a phone number in the Netherlands, Belgium or Luxembourg: community reports, spam and scam categories, a trust verdict, and the registered business if there is one, from the Calmido phone directory. Use it whenever someone asks who called them, whether a number is safe, spam or a scam, or which company a number belongs to. Accepts international (+31 20 123 4567) and national (020 123 4567) formats; pass `country` for a national number outside the Netherlands.
