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.
