# Digital NZ API (api.digitalnz.org/v3)

`GET https://api.digitalnz.org/v3/records.json?text=<term>[&api_key=<key>]`.

With **no `api_key` parameter at all**, the request succeeds outright:

```
HTTP/2 200, content-type: application/json; charset=utf-8, content-length: 66035
{"search":{"page":1,"per_page":20,"result_count":413416, "results":[...]}}
```

This host is genuinely keyless for reads — no auth header, no query-string key,
nothing. But supply a **wrong** `api_key` and it is refused:

```
GET ...&api_key=bogus0000000000000000000000000
HTTP/2 403, content-length: 28
{"errors":"Invalid API Key"}
```

The inversion that matters for an agent: omitting the parameter entirely is the
*safe* path here, and fabricating or guessing a plausible-looking key value is
the one thing that breaks a call that would otherwise have worked. (Contrast
with DPLA and Trove in this lane, where omitting the key is *also* a 403/401 —
Digital NZ is the one of the three where "send nothing" is strictly better than
"send something wrong.")
