The Phone Verification API provides a two-step flow: send a one-time code to a phone number, then verify the code. The system detects carrier type, virtual numbers, and disposable phones.

​
Endpoints

Send Phone Code

POST /v3/phone/send/ — Send a one-time verification code via SMS.

Check Phone Code

POST /v3/phone/check/ — Verify the code and retrieve phone risk data.

​
How it works

  1. Call Send Phone Code with the phone number in E.164 format (e.g., +14155552671)
  2. The user receives a code via SMS (valid for 5 minutes)
  3. Call Check Phone Code with the phone number and code
  4. Receive verification result plus risk signals (carrier type, virtual number detection)
