# Trove API v3 (api.trove.nla.gov.au)

`GET https://api.trove.nla.gov.au/v3/result?q=<term>&category=book&encoding=json`.

No key at all:

```
HTTP/2 401, www-authenticate: Key, content-length: 96
{"message":"No API key found in request","request_id":"eb1dbf56122d4806edec6d018cf93b1d"}
```

A header `X-API-KEY: bogus123456`:

```
HTTP/2 401, www-authenticate: Key, content-length: 81
{"message":"Unauthorized","request_id":"b5972c5e5bc2891d7e8f4461aea42605"}
```

Unlike DPLA (identical message for missing vs. bogus key, recorded separately
in this lane), Trove gives **two distinct messages** — "No API key found in
request" vs "Unauthorized" — so a client can at least tell "I forgot the
header" from "I sent a wrong key" without any other signal. Both responses
carry the same `www-authenticate: Key` header and a fresh `request_id` each
call (not request-deduplication-safe to retry blindly on that id).

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.
