Apier.no is a compliance infrastructure API between AI agents and Norwegian government infrastructure.

Apier.no sits between AI agents and Norwegian government infrastructure (Altinn 3, Brønnøysund Enhetsregisteret, Skatteetaten). It answers three questions that otherwise require weeks of integration work:

Authorization — can this agent legally act for this company?
Obligations — which regulatory filings apply, with what deadlines?
Action translation — how do we turn a business intent into a safe, auditable submission?

Every response is deterministic, versioned against a Universal Rulebook, and carries a _meta block so agents can reason about data freshness.

Quick start

The step-by-step walkthrough lands in a follow-up PR; today the page points at the zero-auth endpoints you can try now.

Endpoint reference

Authoritative contract at /openapi.json. Browsable per-endpoint pages land in a follow-up PR.

Sandbox

Hit the live public endpoints without an API key.

Examples

Golden-path agent workflows cross-checked against the capabilities manifest.

Authentication

Every request to Category B endpoints carries an API key in the Authorization: Bearer <YOUR_API_KEY> header. Keys are stored as SHA-256 hashes and scoped per API key, with rate limits per tier. Category A endpoints (discovery, public obligations, public deadlines) require no auth at all — they exist for agent build-vs-buy decision loops. See Authentication for the full model.
