## Tools (as reported by the server, not verified)

- `phone\_lookup`: Return a supplementary, low-confidence intelligence bundle for a phone number: validity, formatting, line type, range carrier, country, caller name \(CNAM, where available\), STIR/SHAKEN verstat \(supply the call's verstat to fold it into the spam signal\), a labeled spam signal, and a first-party do-no
- `line\_type`: Return only the deterministic fields for a number — validity, line type \(mobile / fixed line / VoIP / …\), range carrier, country, and formatting. No paid dip; a free, fast classification a voice agent can call before deciding to enrich.
- `caller\_risk`: Return a labeled, low-confidence risk read for an inbound caller: a spam signal \(0–100, higher = riskier\), verstat passthrough, and a first-party do-not-contact \(DNC\) signal — without a name dip. A supplementary input to the agent's own policy, never a verdict on whether to accept or reject the call
- `dnc\_check`: Return a first-party do-not-contact signal \(suppress / no\_match / unknown\) for a number, sourced ONLY from suppression preferences registered and verified by the number's own owner inside Numbers Online — never a copy of any government or licensed do-not-call registry. "suppress" = the owner asked n
