Usage

This is not an app but rather a set of snippets showing how Nexmo Number Insight can be used to validate and clean up numbers, as well as be used to determine the channel type and cost of a number.

The scripts are:

• 1_country_code.rb shows how to find the country code for a number
• 2_cleanup.rb shows how to turn a local number into its international format
• 3_channels.rb shows how to extract more details, like the channel format (landline or mobile) from a number
• 4_cost.rb shows how to calculate the cost of a call or SMS to a number
• 5_validation.rb shows how to verify that a number is likely to be valid
