# GNews.io — 400, not 401, and missing/wrong key return the identical message

GNews (`gnews.io/api/v4`) is keyless-refused like NewsAPI, but with a
materially different status code and far less information in the body.

## Probe

```
curl -s -D - "https://gnews.io/api/v4/top-headlines?country=us"
curl -s -D - "https://gnews.io/api/v4/top-headlines?country=us&apikey=fakekey123"
curl -s "https://gnews.io/api/v4/top-headlines?country=us&token=fakekey123"
curl -s "https://gnews.io/api/v4/search?q=test"
```

## Observed

- No key → **HTTP 400** (not 401), `content-type: application/json; charset=utf-8`,
  `access-control-allow-origin: *`, `x-robots-tag: noindex`:
  `{"errors":["You did not provide an API key."]}`
- `apikey=fakekey123` (the documented query-param name) → **HTTP 400**,
  **the identical body**: `{"errors":["You did not provide an API key."]}` —
  a syntactically well-formed but wrong key is reported exactly as if no key
  were sent at all, with no separate "invalid key" message anywhere.
- `token=fakekey123` (a plausible alternate param name) → same identical body —
  confirms the gate does not even echo back which key-bearing param it saw;
  it only knows "valid key present" or not, with one undifferentiated error
  either way.
- `/api/v4/search` (the other headline endpoint) → same keyless-refusal shape,
  same message, confirming this is a global auth gate, not one path's.

Chosen status code (400 vs the far more common 401/403 for this exact failure
class) is itself the gotcha: code that branches on HTTP status to detect "no
key" will miss this host if it only checks for 401/403.

How observed: 2026-10-05, curl, keyless and two differently-keyed GETs against
`gnews.io/api/v4`.

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.
