Number Lookup Overview

The Phone number lookup API allows users to lookup phone number data.

Two APIs are currently available - private API and public API. Public API shows part of the data we have available and can be used by everyone free of charge. Additionaly, public API does not support fetching caller name and carrier data and can be used without registration or token. In order to use private API user has to register and create API token on Telnyx portal.
