The firmafind API: Integrate Austrian company data directly into your app

2 min

If you manage a CRM, run a B2B online store, or build onboarding tools, you need reliable company details. Usually, this means searching registers by hand, downloading PDFs, and manually typing details into your database.

This process wastes time and introduces typos.

To solve this, we are launching the firmafind API: a simple way to query official registry data programmatically.

What the API does

Our API is a REST interface connecting you to data for over 500,000 Austrian businesses.

Real-time company search

Search by company name or company register number (FN) to find matching businesses instantly.

Structured master data

Retrieve clean JSON payloads containing:

  • Legal forms and registered offices
  • Managing directors and authorized signers
  • Addresses and company status (active, deleted, or in liquidation)

PDF and XML downloads

Download official documents like articles of association, balance sheets, and annual financial statements directly.

Quick curl example

Here is how you query a company by its registration number:

curl -X GET "https://firmafind.at/api/companies/123456a" \
  -H "x-api-key: YOUR_API_KEY"

The response returns structured JSON data:

{
  "success": true,
  "data": {
{{ ... }}
    ]
  }
}

Practical use cases

  • Automated onboarding: Validate registration numbers and billing addresses during checkout or signup.
  • CRM updates: Automatically fill in address details and managing directors when a salesperson adds a new lead.
  • Risk monitoring: Check if partners or vendors are active or entering insolvency proceedings in the background.
