List the companies a person holds interests in

GET
/persons/{person_id}/holdings

Shareholdings in which this person is the holder: shares in a GmbH or UG (shareholder), a Kommanditist's interest (limited_partner) and a Komplementär's (general_partner), each with the company it is in. A holding has the same id as the same interest on GET /companies/{company_id}/shareholders. Read here, its holder is this person, linked; on the company's list it is the holder as the filing names it, whose holder.id can be null. The most confident matches come first.

A Komplementär both represents the KG and holds an interest in it, so they also have a general_partner role at GET /persons/{person_id}/roles. The interest is listed for as long as that role is current, and it is the shareholding the KG's own GET /companies/{company_id}/shareholders lists for them.

Costs 10 credits.
