## 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 norway-company-change-feed-80d4b118
```

Example prompt: Pull all Norwegian company changes from the Brønnøysund Register Centre since January 1, 2024, filtered to these three organisation numbers: 912345678, 923456789, 934567890 — and give me up to 100 results.

## When to prefer this

Use this endpoint when you need to continuously monitor or sync Norwegian company data from the official Brønnøysund Register Centre, particularly for KYB compliance workflows, supplier/customer watchlists, or incremental database synchronisation. It is the right choice when you need cursor-based pagination for large change volumes or want event-type filtering (new, changed, deleted). Prefer it over a full company lookup when you only care about what has changed since a known point in time, not the full profile of a single company.

## Known failure modes

- Missing 'siden' parameter when no 'orgnr' is provided — returns an error requiring at least one of the two
- Invalid date/datetime format for 'siden' — returns a parsing error
- More than 20 organisation numbers provided in 'orgnr' — rejected with a limit error
- 'antall' outside 1–100 range — returns a validation error
- Upstream Enhetsregisteret unavailable — may return a 5xx or empty result
- Stale or invalid cursor passed as 'siden' — may return no results or an error

## How this service works

Change feed from the official Bronnoysund Register Centre (Enhetsregisteret): Norwegian companies registered, changed or deleted since a date, datetime or cursor, optionally only for a watchlist of up to 20 organisation numbers. Returns org number, change type (Ny, Endring, Sletting, Fjernet, Ukjent), timestamp and update id per event, totals and a paging cursor. Use it for KYB monitoring, supplier or customer watchlists and syncing a company database.

## Output

A JSON object containing: the data source identifier, the since parameter used, a breakdown of change type counts (Ny, Endring, Sletting), a timestamp of retrieval, column names for the events array, the next paging cursor (neste_id), the total number of matching events, and an array of change events each containing organisation number, change type, timestamp, and update ID.
