How this service works

Before your agent sends an OTP or SMS: check the number is active and reachable and assess fraud risk — SIM-swap and port-out (MNP) signals, SMS deliverability, non-fixed VoIP and disposable-number flags from a live carrier-network HLR lookup (active line, current carrier, roaming)

Output

Returns a JSON object with: E.164-normalized phone number, validity flag, active status, carrier details (MCC, MNC, operator name, country), line type (mobile/landline/VoIP), roaming status, MNP porting info, and a risk assessment (level, VoIP flag, recently-ported flag, absent-subscriber flag). Also includes provenance metadata: data source (hlr-lookups), freshness kind (live), and fetch timestamp.

Example use cases

Example prompt

“Can you do a live carrier and risk check on the phone number +33612345678 — I need to know if it's active, what network it's on, whether it's been ported recently, and if it's flagged as VoIP or high risk?”

Technical details

Endpoint

GEThttps://api.invoket.com/phone/resolve?utm_source=zero.xyz

When to prefer

Use this endpoint when you need real-time, live HLR data about a phone number's current network status, activity, and risk profile — especially for fraud prevention, user verification, or routing decisions. Prefer this over static number parsing libraries when you need to know if the number is currently active, has been ported, or is flagged as a VoIP/risk number.

Side effects

Invalid or malformed phone number format — returns validation error
Number not found in HLR network — may return valid:false or absent_subscriber:true
Network timeout from HLR carrier — service may return an error or degraded result
Unsupported country or number range — carrier info may be null
Payment failure (x402) — call not executed if USDC payment is not settled

Reviews

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
