Company data by CUI

One call returns the company record. Put the CUI (tax code) in query; the RO prefix works too. A CUI with a wrong check digit gets the error invalid_cui and is not counted.

curl -H "X-API-Key: lg_your_key" \
  "https://leadgen.adrianhomelab.com/lookup_business?query=2816464&fields=companyName,cui,registrationCode,legalForm,county,website,phone,status,anaf,latestFinancials,risk"

fields keeps only the fields you ask for. Without it you get the full record: address, registration date, every CAEN code, the directors and a link to the public record. Without a key, leave out the X-API-Key header.

A real answer, copied on 19 October 2026. The figures change when ONRC publishes a new register or the firm files new accounts.

Checking a company with ONRC and ANAF

The same answer says whether the firm is still active and what ANAF knows about it:

What we do not check: the insolvency bulletin (BPI), debts to ANAF, court cases and shareholders. The answer lists them in risk.notChecked. What the data covers.

Exporting companies by CAEN code and county

lookup_by_category returns the firms with a CAEN code, in one county if you name it. Only active firms by default, newest first. Narrow the list by legal form, revenue, employees, VAT and main activity. With format=csv you get a file that opens in Excel.

# electrical installation firms (CAEN 4321) in Cluj, as CSV
curl -H "X-API-Key: lg_your_key" -o firme-4321-cluj.csv \
  "https://leadgen.adrianhomelab.com/lookup_by_category?category=4321&county=Cluj&main_activity_only=true&format=csv"

Not writing code? The same list can be made in the browser: make a company list in the Leadgen app.

Frequently asked questions

How do I check a company by CUI?

Call GET /lookup_business?query=<CUI>. The answer has the ONRC status, the ANAF data (VAT, e-Factura, inactivity), the latest filing and a risk level with its reasons. A CUI with a wrong check digit is not counted.

Where does the data come from?

The register comes from the dataset ONRC publishes on data.gov.ro. Financial statements come from the Ministry of Finance, fiscal status from ANAF's public web service. One exception: when you ask for contacts, we read the firm's public website.

Can I export the firms in a CAEN code?

Yes. GET /lookup_by_category?category=<CAEN code>&county=<county>&format=csv returns a CSV, active firms only by default. If you do not write code, the same list can be made in the Leadgen app.

What does it cost?

Without a key you get 5 lookups a day, and 25 lookups with a free key. Pro has 500 lookups a day, Business 5,000 lookups. The prices are on the pricing page.
