Single organization

Look up one federal organization by integer ID, returning its full 17-field record plus its parent, immediate children, and full ancestor chain in a single call. Useful for rendering breadcrumbs, expanding tree nodes, or joining a downstream dataset against the org tree without extra round-trips.

Parameters

• organization_id (path) - Integer org ID. Non-integer returns 422; unknown ID returns 404.

  },
  "parent":    { /* 9-field list-shape row; null for root departments */ },

Example

curl -H "Authorization: Bearer YOUR_API_KEY" \
  "https://govconapi.com/api/v1/federal-hierarchy/300000188"

Errors: 401, 404 (unknown ID), 422 (non-integer path), 429.

Note: data is the full 17-field record; parent / children / ancestors are the 9-field list shape. hierarchy_path is the ordered list of ancestor IDs (root first), the same source used to build the inline ancestors array.
