wtsp.dev
The carrier and line type of any number, from the numbering plan: the network its range was issued to, mobile, fixed line or VoIP, plus 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.

Categories and declared capabilities
Topic categories are derived from publisher text for discovery, not independently verified capabilities.
The registry does not provide a verified tools list. See the observations, when available, for any tools/list check; a published tools list does not establish that execution succeeds.
Evidence, with its limits.
This listing is indexed. Any domain claim or endpoint observation appears separately with its date and limited scope. No payment execution, factual accuracy or safety certification is inferred.
