NSW FuelCheck (`api.onegov.nsw.gov.au/FuelCheckRefData/v1/`) is the opposite
of the UK/France/Spain/Italy/Germany feeds in this batch: there is no
keyless path at all — every call needs a registered OAuth-style token, and
the refusal shape is clean and informative rather than a generic block page.

**Probe**

```
GET https://api.onegov.nsw.gov.au/FuelCheckRefData/v1/fuel/prices
```

HTTP **401**, `Content-Type: application/json`:
```
{"errorDetails":{"code":"TokenValidationError","message":"Access token is not valid."}}
```
— a structured application-level error, not an HTML challenge page or a bare
WWW-Authenticate 401 with no body, and not the generic Cloudflare/Incapsula
block pages seen elsewhere in this batch (Ofcom, companion record).

CORS preflight headers on this same response reveal the exact header names
the live API expects a real client to send:
`access-control-allow-headers: origin, x-requested-with,accept,content-type,
apikey, Authorization, if-modified-since, transactionid, requesttimestamp`
— `apikey`, `transactionid`, and `requesttimestamp` are FuelCheck-specific
custom headers beyond the standard `Authorization`, discoverable from this
CORS header alone without reading the developer portal.

`access-control-allow-methods` lists `GET, PUT, POST, DELETE, OPTIONS` —
the gateway accepts all five verbs at the HTTP layer for CORS purposes;
this is the CORS policy advertising what's allowed cross-origin, not a
statement about what this specific path implements, so it is recorded as
the gateway's stated capability, not evidence this endpoint itself is
writable.

No request body, query param, or header variation was sent in testing this
refusal beyond the plain GET above — the finding is the shape of the clean
401 itself, confirmed from a single read-only probe.

`access-control-max-age: 3628800` (42 days) on this same response is an
unusually long CORS preflight cache lifetime for a government gateway —
most APIs cap this well under a day.

How observed: 2026-10-05T12:08:43Z UTC, `curl -D -` GET, default UA, no auth
header, against `api.onegov.nsw.gov.au`.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
