Build company lists

Filter companies by industry, region, size and more with Search & Export.

search-organizations finds companies by their characteristics instead of by name. You combine filters, sort by KPIs and page through the results. To get the list as a file, you export it in the web app.

Combine filters

Filters go into the parameter filters as a JSON object. All filters apply together. If you give several values in one filter, it is enough for one of them to match.

200 · Example response: active GmbHs in Gunzenhausen

Characteristic
Characteristic	Filter
Region	`state`, `county`, `city`, `postal_code`; radius with `location_coordinates` and `location_max_distance_km`
Industry	`industry_code`, a five-digit code of the WZ 2025 such as `62.10.1`, also as a list
Legal form	`legal_form_code`, such as `GmbH`, `AG` or `UG (haftungsbeschränkt)`
Status	`status` (`ACTIVE`, `INSOLVENT` …) or `active` (true, false)
Size	`company_size_category` by balance sheet, `emp_size_category` by employees: `micro`, `small`, `medium`, `large`
KPIs	`financial_filters` with ranges, such as `{"emp_count": {"gte": 50}}`
Registration	`registration_date_from`, `registration_date_to`
From Pro	`owner_filters`, `ownership_filters`, `executive_filters`, `lifecycle_filters`: shareholders, ownership structure, management, insolvency

All filters with their values are listed under search-organizations. total is usually an upper bound of the number of results. From 10,000 results on, it is an estimate.

Sort

With sort and order you set the order, for example by revenue, employees, total assets or registration date. Companies without the value come last. The example searches for GmbHs with at least 50 employees in the district and sorts by revenue.

200 · Example response: the GmbHs with the highest revenue in the district of Weißenburg-Gunzenhausen

With match_context=1, each result shows under _match_context why it matches, for KPIs with the year of the value. This matters because the most recent statement of each company can come from a different year. The result doesn't contain the revenue itself; you fetch it with financial_kpi through fetch-organization.

Without sort, a search with q sorts by relevance. For pure filter queries, set sort when the order matters.

Page through results

limit sets how many results a page has, at most 30. skip skips results: the second page starts at skip equal to limit.

200 · Example response: second page of the active GmbHs in Gunzenhausen, three results each

Each page costs 1 credit, even a page without results. So large pages are the cheapest per company.

A search goes up to result number 10,000. For larger sets, split it up, for example by state, postal code or registration period.

Export the list

You get a file in the web app: in Search & Export, set the filters and choose “Export”. The export returns up to 5,000 companies as CSV, XLSX or JSON.

Before it starts, you see the upper bound and the costs. The export leaves out companies without a published address; on request it includes them. You find the finished file under Account › Exports.

The export reads the results only when it runs. So changes up to that point are included. Through the API, you build the same list page by page as shown above.

Common pitfalls

Write values exactly: status in upper case, registration_number without “HRB”, industry codes with five digits. Unknown values return 0 results, and the page is still charged.
Filters from Pro: owner_filters and the other Pro filters need a Pro or Max credit subscription. Otherwise the API responds with HTTP 403, at no cost.
Register number in the search term: q searches names. For a register number, use the filters registration_authority_name and registration_number.
Empty q: An empty q= returns HTTP 400. Leave out q when you only filter.
