| Tool | Description | Behaviour |
|---|---|---|
| fetch | Retrieve who is behind a phone number from the Calmido directory: the community verdict, the number of reports, the most reported category and the registered business, with a link to the evidence. The id is the one `search` returned: the number in E.164 digits. | Read-only |
| lookup_phone_number | 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. The verdict is one of: business (no reports, a known registered business), empty (no reports and no known business: not a sign that the number is safe), neutral (reported, but not enough evidence to flag), safe (reported, and the community found nothing alarming), suspicious (flagged as a threat), restricted (the identity was erased on request; the reports remain) or unavailable (the lookup could not be read: it says nothing about the number). An invalid number returns an error. Calls are rate limited per address; over the limit the error says how many seconds to wait. | Read-only |

Pass its id to `fetch` for the verdict and reports. | Read-only |
