Bli kjent med Apier

“Bli kjent med Apier” is Norwegian for “get to know Apier”, and that is exactly what this page is for.

Apier is a small Norwegian company with one clear job: giving AI agents machine-verifiable facts about Norwegian companies and the register's coded signing rules for each of them. Norway runs some of the most digitised government infrastructure in the world: Brønnøysundregistrene for the company registers, Maskinporten for machine-to-machine authentication, Altinn for dialogue between businesses and the state, and Skatteetaten for tax. Each of them is excellent at what it does. Each of them also comes with its own documentation, its own authentication model, its own data formats, and its own quirks.

If you have ever tried to read company status, roles and signing authority reliably from software, you know how the story goes: weeks of reading, data formats that differ between registers, and coded signing rules that are easy to get wrong. Apier exists so your agent can skip that part. It calls one API or one MCP server, and every answer comes back with its source, the time it was read and, when you ask for one, a signed receipt. Binding government submission is not live.

What Apier is

In general terms, Apier is a translation layer. On one side sit your AI agent, or the software that runs it. On the other side sit the public registers. In between, Apier speaks both languages: it answers questions like “does this company exist, and is it active?”, “who does the register say may sign for it?” and “which obligations and deadlines apply to a company like this?”. Every answer comes back in one consistent, machine-readable shape, with a note about where the data came from and when it was verified.

We are deliberately not a data broker. We do not sell lists of companies. The value is the understanding: what applies, who the register names with signing authority, and when things are due, kept up to date against the authoritative sources, so you do not have to keep four mental models in your head.

Who it's for

One audience: AI agents, and the developers or companies that run them. An agent that onboards, pays or signs for a Norwegian company needs to know the company is real and active, and who the register says may sign for it, before it acts. Apier gives it those facts with their source and time, so the developer behind it can show later exactly what was checked.

Why it exists

Because the hard part of knowing who can act for a Norwegian company was never the information: it is public. The hard part is the distance between “the information exists somewhere” and “my software can act on it reliably”. Every team that bridges that distance builds the same bridge, alone, again. We thought that was a waste, so we built the bridge once and made it a product. Norway's digital infrastructure deserves to be easy to build on, for people here and for anyone abroad who works with Norwegian companies.

If that sounds useful, the documentation shows the API in detail, and the sandbox lets you try it with synthetic data. No account, no commitment. Velkommen.
