Notes
Read only JSON API at https://api.wikitree.com/api.php. Public profiles need no sign in. Private profiles need the user to sign in to WikiTree through clientLogin, and return data only to members on that profile's Trusted List. Lineage sends appId=LineageAPI. The App Policies page answered with a bot check to our fetch, so it was not read.
