The European unique identifier the register shows for the company, LURCSL.B82454 in the sample.

Can I see publications?

Use Luxembourg company filings, which lists RESA publications.

Do I pay for lookups that come back empty?

No. You are charged per result, so a request that finds nothing costs nothing. Testing this against a messy list is free to get wrong.

What does a lookup cost?

5 points per resolved lookup, which is $5 per 1,000, and only successful lookups are charged. Points come out of your monthly plan allowance, so there is no separate per-country contract.

Corporate registry

Luxembourg Company Registry (LBR / RCS) API and MCP — Company Profile by RCS Number

Send an RCS number and get the company as structured JSON: name, status, legal form, registration date, address broken into street, postal code and city, trade names, NACE code with description, and the EUID.

Run it in the app Read the API docs

You send: a Luxembourg RCS number, or the link to the company page
You get back: status, legal form, registration and deletion date, address, trade names, NACE code and EUID
Coverage: Luxembourg — entities on LBR / RCS.
Price: 5 pts — $5 per 1,000; Charged only when the record resolves. A lookup that finds nothing is not billed.

Comparison

Ways to get this data

Three approaches teams use today, and where each one runs into trouble.

Approach	What it takes	Cost	Trade-off
LBR / RCS directly	Open LBR / RCS and read the record	Usually free, sometimes per-document	A different interface, language and data shape for every country you add
Collecting it yourself	Build and host a crawler per register, then keep each one alive	Infrastructure and maintenance	Registers change their pages without warning, and nobody is on the hook when yours breaks
NeuralVerge	One request, the same shape as every other source in the catalog	$5 per 1,000, misses not billed	Covers Luxembourg — other countries are separate sources with the same request format
