Numbers Online — phone intelligence

Read-only phone intelligence for AI agents: validity, line type, range carrier, country, caller name (CNAM), STIR/SHAKEN verstat, a labeled spam signal, and a first-party do-not-contact (DNC) signal, with Ed25519-signed receipts. Every field is a supplementary, low-confidence signal; the calling agent keeps every routing and dialing decision.

Skills

• 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, 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.

• Line type
  Return only the deterministic fields for a number — validity, line type (mobile / fixed line / VoIP / …), range carrier, country, and formatting. Free, fast classification; no paid dip.

• 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 a call.

• 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. Comes with a signed receipt recording the status "as of T". Advisory only.
