Check an Austrian company by API: Firmenbuch
Firmenbuch · not covered yet · checked
The official route
The Austrian Firmenbuch has had a free API since 2025-03-17, under the EU rule on high-value datasets. It covers company data, documents and accounts.
You apply in JustizOnline, at justizonline.gv.at/jop/web/iwg, under "Antrag zur Informationsweiterverwendung" (application for reuse of information). The login is ID Austria or EU-Login. We read the terms on that site on 2026-11-09. As we recorded them:
- The API is free, and the key comes within about 5 working days.
- CC BY 4.0 is the fallback licence.
- You name the source as "Republik Österreich vertreten durch das BMJ".
- Changes to the data must be marked.
Besides the free API there are paid licence products, at EUR 90 once plus EUR 90 a month.
Where it gets hard
- The login. You need ID Austria or an EU eID. We have not tested whether a foreign eID gets through EU-Login.
- The terms do not cover passing raw data on, essentially unchanged, to unrelated companies. A lookup API that returns one company's record per call does roughly that. So we have not built on it, and we have not decided whether we will.
- It is an application with a wait of about 5 working days, so there is no quick test call.
One call
No single call from us reads the Firmenbuch today. For an Austrian company, counterparty-check still returns:
| Check | Source for this country |
|---|---|
| Register status | The LEI record (GLEIF), when the company has an LEI |
| LEI status | GLEIF |
| VAT number | VIES |
| IBAN | ISO 13616 check digits; no bank is contacted |
| Company on sanctions lists | OFAC, UN, UK, EU and US export lists |
| Recent accounts | ESEF annual reports, listed companies only |
The insolvency check comes back unverified for Austria. Is the Firmenbuch the register you need? Write to support@boscolabs.dev. We use those mails to decide what to build first.
What we do not cover
- Firmenbuch status, documents and accounts.
- Insolvency in Austria.
- Officers and owners.
- The LEI record is what the company told its LEI issuer at the last renewal. It is not the register.
Sources
- JustizOnline, reuse of information:
justizonline.gv.at/jop/web/iwg - GLEIF, where the LEI record comes from
- VIES VAT number validation
