## 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 getapi-property-energy-label-lookup-5e5bc9f0
```

Example prompt: What is the official energy label for the apartment at Keizersgracht 1, 1011AB Amsterdam — is it still valid and what's the energy index?

## When to prefer this

Use this endpoint when you need official Dutch energy label data (energy class A–G, energy index, validity) for a specific residential or commercial property identified by Dutch postcode and house number. Prefer this over generic property APIs when the query is specifically about Dutch EP-online energy certificates, building energy performance, or sustainability compliance for Netherlands-based real estate.

## Known failure modes

- Property not found in register: returns found=false with empty labels array
- Invalid or malformed zip code: returns error or empty result
- House number/letter mismatch: no matching label returned
- Expired or unregistered energy label: record may be absent
- Rate limiting or payment failure: HTTP 402 if x402 payment not processed

Each label entry contains: zip code, energy class (e.g. A–G), energy index (numeric), validity date, house number, optional house letter, building type (e.g. Appartement), construction year, and registration date. Returns found=false if no label is registered for the given address.
