wAILand GDACS Changes
Call this when an agent tracks GDACS disasters (see /v1/disaster-events) and needs what changed since a date: alert-level moves, is_current flips with how long the previous state held, and events entering or leaving Orange/Red scope, each dated to the daily snapshot that first showed it. GDACS publishes episode lists free but never when anything changed; these dates are ours, from 2026-08-25. Orange/Red only. Not for life-safety. Filters: since (required), until, kind, event_type.

wtsp.dev
Whether a number is on WhatsApp and, if so: personal or business account, about text, country, linked devices and whether it runs on the Cloud API.

Query param: phone, with country code (e.g. +14155552671). Every answer is charged, “not on WhatsApp” included; a lookup WhatsApp does not answer is free.
wtsp.dev-$0.006listed

Everything /v1/profile returns, plus the profile photo as a permanent URL and a content hash: an unchanged hash means an unchanged photo. The URL is null when the account has no photo or hides it. Query param: phone, with country code (e.g. +14155552671). Every answer is charged, “not on WhatsApp” included; a lookup WhatsApp does not answer is free.
wtsp.dev-$0.01listed
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).
