wtsp.dev/v1/profile

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. Businesses add their public profile: name, description, categories, email, websites, address, coordinates, hours, join date and Facebook page. No photo; /v1/profile/full adds 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.
