  description: >-
    The Number Verification API enables automatic verification that users
    interact via devices with SIM cards associated with their phone numbers.
    Based on the CAMARA open standard developed by the GSMA Open Gateway
    initiative. Eliminates the need for credential entry or OTPs by using
    carrier network data to confirm the mobile number actively connected
    to the network matches the claimed number.
