    Why it is in this group

    • The name "lookup_phone_number" says "lookup": a word for reading.
    Description, as the server wrote it
    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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
