## 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 dutch-address-lookup-by-postcode-or-coordinates-3e8e36fe -d '<json body>'
```

Example prompt: What is the full address for Dutch postcode 1017CT, house number 1? Or, if you have coordinates, reverse-geocode latitude 52.3676 and longitude 4.9041 to a Dutch street address.

## When to prefer this

Use this endpoint when you need to resolve or validate Dutch addresses by postcode and house number, or when you have GPS coordinates and need the corresponding Dutch street address. It is specifically designed for the Netherlands (NL) address space and is more reliable than a generic global geocoder for Dutch postal data.

## Known failure modes

- Postcode not found or invalid format — likely a 4xx error
- House number does not exist at that postcode — empty or error result
- Coordinates outside the Netherlands — no result or error
- Missing required query parameters — 400 Bad Request
- Payment not processed or insufficient — 402 Payment Required

## How this service works

Dutch address lookup by postcode + house number, or reverse by coordinates. Send the parameters in a JSON request body via POST. Payment constitutes acceptance of the terms at https://agenticweb.nl/terms.

## Output

Returns structured Dutch address data including street name, house number, postcode, city, and municipality — either resolved from a postcode+house number pair or from geographic coordinates.
