wtsp.dev/v1/carrier

The carrier and line type of any number (mobile, fixed line or VoIP), plus its country, region, time zones and national and international formats. Works whether or not the number is on WhatsApp. Ported numbers report their original carrier. Query param: phone, with country code (e.g. +447400123456). Only charged when a carrier is on record; numbers without one (the US and Canada among them) get a free 404.
