corporate_ownership_tree
ActiveTool of io.github.blackboxfoundry/livedatalink
One-call FULL corporate-ownership tree for a company from GLEIF (keyless CC0 reference data). Give a company name or a 20-character LEI; the tool resolves the entity, climbs to its ULTIMATE parent (top of the ownership chain), then walks DOWN from that root to list the reported direct subsidiaries plus one level of grand-subsidiaries, each with its LEI, jurisdiction, and status (entity ACTIVE/INACTIVE + LEI registration ISSUED/LAPSED). The queried entity is marked in the tree so you can see where it sits. Distinct from resolve_entity, which returns the ultimate parent plus a subsidiary COUNT only: this returns the actual subsidiary LIST/tree for M&A, diligence, and counterparty mapping. The tree is capped (about 25 nodes) so a broad conglomerate stays bounded, with an 'and N more' note where GLEIF reports additional subsidiaries. Only relationships an entity self-reports to GLEIF are shown, so coverage varies by company. A failing hierarchy hop is noted, not fatal. Informational public-record synthesis; verify against GLEIF before relying on it.
