## 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-address-geocoding-1a01505b
```

Example prompt: Can you geocode the Norwegian address 'Storgata 15, 0184 Oslo' and give me the official postcode, municipality, and GPS coordinates?

## When to prefer this

Use this endpoint when you need authoritative Norwegian address data from Kartverket, including official address normalization, postcode lookup, municipality codes, cadastral identifiers, and GPS coordinates — all in a single call. Prefer it over generic geocoding APIs (Google Maps, HERE) when Norwegian official data quality, cadastral numbers, or KYC-grade address normalization is required and when cost matters ($0.002 per call).

## Known failure modes

- No matches returned if address is too vague, misspelled, or outside Norway
- Ambiguous queries may return multiple candidates requiring user disambiguation
- Rural or very new addresses may not yet be indexed in Kartverket
- Network or upstream Kartverket API unavailability returns error
- Missing required query parameter 'q' returns a 400 bad request

## How this service works

Norwegian address search and geocoding from the Norwegian Mapping Authority (Kartverket). Free-text lookup of any street address in Norway returns the official address, postcode, postal town, municipality, cadastral numbers (gnr/bnr) and WGS84 latitude and longitude. Use it to validate, normalise or geocode Norwegian addresses for deliveries, forms, maps and KYC. Compact JSON, up to 5 matches.

## Output

Returns a compact JSON object with a list of up to 5 matching addresses, each containing the normalized address string, postcode, postal town, municipality name and number, cadastral numbers (gnr/bnr), and WGS84 latitude/longitude. Also includes metadata: source (kilde), number of matches (treff), and retrieval timestamp (hentet).
