In their words
Their pitchPhone-number intelligence in one call: validity and E.164 normalization, line type (mobile, fixed line, VOIP, toll free, premium rate), country and region, carrier hint, timezones, and a deterministic 0-100 fraud/KYC risk score with a band and reasons. Offline number-plan metadata from Google libphonenumber. Risk indicators only, not a definitive fraud verdict, no live status and no owner identity, the input number is not stored.
