  description: >-
    The MessageBird HLR API provides a way to send Home Location Register
    network queries to any mobile number globally. It allows developers to
    determine which operator a mobile number belongs to in real-time and
    check whether the number is currently active on the network. This API
    is commonly used for number portability checks, fraud prevention, and
    optimizing message routing.
