Caller Information is sourced through CNAM, a database that provides caller name information for phone numbers owned by carriers in the US. This means that not all phone numbers will have available caller name information.

The CNAM database returns additional properties if you request caller name in your GET request, including the owner's name, whether the caller is a business or consumer, and an error code if any.

Here are the specific properties returned by the CNAM database:

Caller name lookups for US numbers are billed per lookup, even if data is not available.

Query Parameters are used to specify the phone number you want information about and the types of information you'd like.

You can specify the ISO country code of the phone number to fetch, especially if the phone number is provided in a national format.

The type of information to return can be carrier or caller-name, and you can specify both by adding the parameter twice.

You can also invoke multiple Add-ons by specifying their unique_name, and each Add-on can have its own data specific to its invocation.

The name of the phone number's owner is an optional parameter, and if it's null, it means the information was not available.

Caller Name Information is sourced through CNAM and only available for phone numbers owned by carriers in the US. This means if you're looking up a number from outside the US, you won't get any caller name information.

The additional properties returned when requesting caller name information include the caller's name and type. The caller's name is a string indicating the name of the owner of the phone number, while the caller type is a string indicating whether the caller is a business or consumer.

Here are the possible values for the caller type:

Caller name lookups for US numbers are billed per lookup, even if data is not available. Requesting caller name lookups for non-US numbers will return null values and will not be billed.
