Number Insight API

Nexmo's Number Insight API provides details about the validity, reachability and roaming status of a phone number, as well as giving you details on how to format the number properly in your application. There are three levels of Number Insight API available: Basic, Standard and Advanced. The advanced API is available asynchronously as well as synchronously.
