# 2 — pull its fully-cited dossier
curl https://whiteintel.dev/api/public/dossier/{id}

# 3 — walk to the ultimate beneficial owner
curl 'https://whiteintel.dev/api/public/ownership-path?root={id}'

/ FAQ

Questions, answered.

No key is needed to start — the public REST API (search, entity, dossier, ownership-path, company, sanctions and offshore-exposure) is free on a monthly allowance. A wi_ key attributes usage to your account and unlocks the higher paid tiers (deep traversal, bulk, monitoring).

https://whiteintel.dev. Every endpoint is under /api/public/. The machine-readable spec is at /api/public/openapi.json and an agent skills descriptor at /api/public/skills.json.

Call entity/search?q=… to get an entity id, then dossier/{id} for the fully-cited dossier, and ownership-path?root={id} to walk to the ultimate beneficial owner.

Yes — npx -y @whiteintel/mcp-server exposes these endpoints as nine tools for Claude Desktop, Cursor or any MCP client. See the MCP page.

"Not yet observed", not "does not exist". WhiteIntel is investigative decision-support with a source on every claim, not a legal determination of beneficial ownership.
