Overview

Returns the GLEIF-curated direct family of an entity: its corporate parent and its direct subsidiaries, one level deep. This is the curated, direct-consolidation view of corporate structure, distinct from the raw, all-relationship-types graph at Owner Related. Family edges come from GLEIF Level 2 (the IS_DIRECTLY_CONSOLIDATED_BY relationship). Coverage is therefore limited to LEI-reporting companies: an absent edge does not mean the entity has no parent or subsidiaries, only that none is recorded in GLEIF. An entity not linked to any others, or a company profile with no GLEIF edges, returns { parent: null, children: [] } (a valid 200, not a 404).

“Family” is a group-level relationship: related companies in a corporate tree. It is never an identity claim: Pfizer Inc (US) and Pfizer AG (CH) are distinct entities connected by family, not the same entity.

import { Signa } from "@signa-so/sdk";

const signa = new Signa({ api_key: process.env.SIGNA_API_KEY });
const family = await signa.entities.family("ent_R3jK9mN2");
console.log(family.parent?.name, family.children.length);
