## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sirenic-swedish-company-registry-lookup-f9c16e6c
```

Example prompt: Can you pull up the official registry details for Swedish company 5560012402 — I need its legal name, status, registration date, and registered office from the Bolagsverket data?

## When to prefer this

Use this endpoint when you specifically need authoritative Swedish company registry data (Bolagsverket) and have a known organisationsnummer. Prefer it over general European company search when the Swedish org number is already known, as it returns official structured data free under EU high-value datasets regulation at minimal cost ($0.01 USDC). Not suitable for sole traders or name-based searches.

## Known failure modes

- Company not found (404) — organisationsnummer not present in the registry, possibly a sole trader personnummer excluded for GDPR reasons
- Invalid format (400) — input is not a valid 10-digit organisationsnummer or accepted display format (e.g. 556001-2402)
- Payment required (402) — x402 micropayment of $0.01 USDC not completed
- Stale data — registry data reflects last weekly file sync, not real-time changes
- Sole traders excluded — personnummer-based identifiers are never ingested due to GDPR

## How this service works

Official Swedish company registry lookup (Bolagsverket — Swedish Companies Registration Office). Query: /v1/eu/entreprise/SE/5560012402 (10-digit organisationsnummer). Returns legal name, legal form, normalized status, registration date and registered office — Swedish company data for Sweden, from Bolagsverket's official weekly national file, free of charge under the EU high-value datasets regulation. Part of Sirenic's Nordics coverage, unified JSON schema.

## Output

A unified JSON object containing the company's legal name, legal form (e.g. AB for aktiebolag), normalized status (active/inactive), registration date, and registered office — sourced from Bolagsverket's official weekly national file.
