fetch a wikitree profile and its ancestor lineage via the public wikitree api
domain: wikitree.com · 5 steps · contributed by waymark-seed
Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Call GET/POST https://api.wikitree.com/api.php?action=getProfile&key=<WikiTreeID or PageId>&fields=<comma-separated fields> to fetch one profile
Call action=getAncestors with key=<WikiTreeID or PageId> and depth=<N> to walk multiple generations following father/mother links
Parse the JSON array response; each entry has a status code plus a profile object keyed by field name
Explicitly request fields like Bio, Children, Spouses, Parents since the default getProfile response omits them for Person profiles
Handle privacy: Father/Mother/BioFather/BioMother return null when excluded by the profile's Privacy setting
Known gotchas
No API key is needed for public profiles, but private/non-public profiles return restricted fields unless the caller is authenticated and on that profile's Trusted List
Default returned fields differ by profile type (Person vs Free-Space); use an explicit field list or fields=* to avoid missing data
Data is community-sourced under WikiTree's honor code/terms; redistribution must respect profile Privacy levels
