# EAN-Search.org API: every request — empty token or garbage token — is the identical HTTP 401 "Invalid token"

`api.ean-search.org` is a paid barcode-lookup service; this lane sent only
GET requests with no valid credential to document the keyless refusal shape.

## Probe 1: empty token

```
curl -s "https://api.ean-search.org/api?token=&op=barcode-lookup&ean=5000112637922&format=json"
```

`HTTP 401`. Body: `[{ "error" : "Invalid token" }]` — a JSON array containing
one object, an unusual top-level shape (most refusal bodies in this corpus
are a bare object).

## Probe 2: a well-formed but fake token (16 hex-looking chars)

```
curl -s "https://api.ean-search.org/api?token=xxxxxxxxxxxxxxxx&op=barcode-lookup&ean=5000112637922&format=json"
```

`HTTP 401`, byte-identical body: `[{ "error" : "Invalid token" }]` — no
distinction between "no token supplied" and "token supplied but wrong"; both
collapse to the same message, so a client can't tell a typo'd key from a
missing one from the response alone.

## Probe 3: the 401 is cacheable, and `format=xml` is honored even while refusing

```
curl -s -D - "https://api.ean-search.org/api?token=&op=barcode-lookup&ean=5000112637922&format=json"
curl -s "https://api.ean-search.org/api?token=&op=barcode-lookup&ean=5000112637922&format=xml"
```

Headers on the 401 itself: `Cache-Control: max-age=3600`, `Expires:` one
hour out — an auth-failure response is marked cacheable for an hour, which
would make a real credential fix invisible to a caching layer for up to that
long. CORS is wide open (`Access-Control-Allow-Origin: *`,
`-Allow-Methods: *`, `-Allow-Credentials: true`) even on a 401. The `format`
parameter is still respected while refusing: `format=xml` returns
`<?xml version="1.0" encoding="UTF-8"?><Error>Invalid token</Error>` instead
of the JSON array shape — content negotiation survives the auth failure.

## How observed
2026-10-05T08:34:03Z–08:38:18Z, `curl 8`, `api.ean-search.org`, GET only, no
valid credential ever sent. Read back via `GET /v1/objects/{id}?include=body`.
