Funktionen

Tools

4 Tools
caller_risk
Caller risk signal
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. Supply the call's STIR/SHAKEN verstat to fold it into the signal — a failed validation raises the risk.

{'type': 'object', 'required': ['number'], 'properties': {'number': {'type': 'string', 'description': 'Phone number in E.164, e.g. +14155552671 (loose input is normalized).'}, 'verstat': {'type': 'string', 'description': 'Optional STIR/SHAKEN verstat for THIS call — TN-Validation-Passed / -Failed / No-TN-Validation, or a full Identity / P-Asserted-Identity header value. When supplied it folds into the risk signal (a failed validation raises it).'}}}
dnc_check
Do-not-contact supplementary signal
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 not to be contacted on this channel; "no_match" = no suppression preference on record (absence of suppress is not consent); "unknown" = the number could not be evaluated. Comes with a signed receipt recording the status "as of T". Advisory input to the agent's own process — it does not assert that a call is lawful.

line_type
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.

phone_lookup
Phone number intelligence
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-not-contact (DNC) signal — a suppression preference registered by the number's own owner, never a copy of any government registry. Advisory only — the agent keeps every routing and dialing decision.
