Lookup

The Lookup API provides real-time data about phone numbers and IP addresses. It can be used to retrieve carrier information, caller name (CNAM), number portability data, toll-free routing details, and geolocation of IP addresses.

Use Lookup to validate numbers before routing calls, enrich logs with geographic or carrier metadata, or determine responsible organizations for toll-free numbers.
