How this service works
Phone-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.
Output
Returns E.164-normalized number, validity flag, line type (mobile/fixed/VOIP/toll-free/premium), country, region, carrier hint, associated timezones, and a deterministic 0-100 risk score with a risk band label and human-readable reasons explaining the score.
Example use cases
Example prompt
“Can you run an intelligence check on the phone number +14155552671 — I need to know if it's valid, what line type it is (mobile, VOIP, etc.), and what its fraud risk score is before I approve this new user signup?”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/phone/intel?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, offline-capable phone number validation combined with KYC/fraud risk scoring in a single call — especially for onboarding flows where you want to flag VOIP, premium-rate, or suspicious numbers before allowing account creation. Prefer this over live number lookup services when you don't need real-time active-status or owner identity, and when privacy matters since the number is not stored.
Side effects
- Missing 'number' query parameter returns 400/validation error
- Ambiguous national-format number without country code may fail to parse
- Unrecognized or unparseable number string returns invalid/error response
- Payment not sent or incorrect amount returns 402 Payment Required
- Numbers from territories with incomplete libphonenumber coverage may have reduced accuracy
