Base fields

entity_id string

Stable handelsregister.ai identifier (32-char hex string).

name string

Registered legal name of the entity.

status enum

ACTIVE, TERMINATED, DISSOLVED or INSOLVENT.

legal_form string

Legal form (GmbH, AG, KG, …) when available.

address object

Postal address with street, house_number, postal_code, city, county, state, country and coordinates.

registration object

Register record with court, register_type and register_number.

Initial entry into the commercial register (ISO date).

purpose string

Stated business purpose (Unternehmensgegenstand).

representation_scheme object

General representation scheme: { current: [...], history: [...] } with effective_from/effective_to per version.

capital object

Registered capital: { current, history }. current carries amount, currency and kind (STAMMKAPITAL, GRUNDKAPITAL, HAFTSUMME, GENEHMIGTES_KAPITAL, BEDINGTES_KAPITAL, VARIABLES_KAPITAL — open enum); each history entry has value, effective_from and effective_to (null = still in force). change_amount on a history entry is unsigned and does not always equal the difference between two consecutive amounts, so derive increases and decreases from the amounts. Partnerships and other entities without registered capital return current: null and an empty history.

contact_data object

website, phone_number and email when available.

industry_classification object

Industry codes per WZ2008 and WZ2025 with labels.

keywords array<string>

Keywords derived from the business purpose.

products_and_services array<string>

Product and service descriptions when available.

history array<object>

Chronological log of all register changes (name, seat, capital, representation, …).

features=financial_kpi

financial_kpi array<object>

Per fiscal year: revenue, employees, active_total (balance-sheet total), net_income, material_expenses, personnel_expenses. Every year names the source of its figures in _provenance: statement_type (Jahresabschluss = annual accounts, Bilanz = balance sheet only, Konzernabschluss = consolidated accounts; null for market data), period_start and period_end of the fiscal year, plus exempt_subsidiary and parent_organization ({ entity_id, name }). With exempt_subsidiary: true the company published the consolidated accounts of parent_organization instead of accounts of its own, so that year's figures cover the whole group.

features=balance_sheet_accounts

balance_sheet_accounts array<object>

Per fiscal year: hierarchical balance-sheet line items from the published statement, with _provenance naming the source of the figures (fields as in financial_kpi). For energy utilities, Max accounts also receive activity_statements through the API: the balance sheets of the activity statements (section 6b EnWG), one per regulated activity such as electricity or gas distribution; together they do not add up to the company's balance sheet.

features=profit_and_loss_account

profit_and_loss_account array<object>

Per fiscal year: hierarchical profit-and-loss line items, with _provenance naming the source of the figures (fields as in financial_kpi). For energy utilities, Max accounts also receive activity_statements through the API: the profit and loss accounts of the activity statements (section 6b EnWG), one per regulated activity.

features=related_persons

related_persons object

Authorized representatives: { current: [...], past: [...] } — managing directors, board members, signatories. Each person carries organization_representation_scheme and role_representation_scheme (current scheme + history).

features=shareholders

shareholders object

Shareholders: { total_capital, entries: [...], history: { current_as_of, past: [...] } }. Each entry carries shareholder, contribution, contribution_ratio and role; history.past delivers previous shareholder lists with an as_of date. total_capital, contribution and contribution_ratio may be null (e.g. for partnerships).

features=ubos

ubos object

Ultimate beneficial owners: { beneficial_owners, unresolved_beneficial_owners, coverage } as recorded in the transparency register.

features=shareholdings

annual_financial_statements__html array<object>

Published annual statements with document_html (rendered HTML), document_type, document_title, document_date, language and year.
