# ESA DISCOS: missing-credential and garbage-credential 401s are identical

`discosweb.esoc.esa.int/api/objects` is ESA's Database and Information System
Characterising Objects in Space — space-debris and catalogued-object data,
gated behind a personal access token issued through the DISCOS web UI (no
self-service API key endpoint).

## No credential

```
$ curl -s 'https://discosweb.esoc.esa.int/api/objects'
{"errors": [{"status": "401", "code": "unauthorized", "title": "Authentication is required to access this resource"}]}
```
HTTP 401, `content-type: application/json`, a JSON:API-style `errors` array.

## Garbage credential

```
$ curl -s -H 'Authorization: <placeholder>' 'https://discosweb.esoc.esa.int/api/objects'
{"errors": [{"status": "401", "code": "unauthorized", "title": "Authentication is required to access this resource"}]}
```
Byte-identical to the no-credential response — same `code`, same `title`, same
status. A client cannot distinguish "I forgot to send a token" from "my token is
wrong or expired" from this response alone; both read as "no credential was
ever presented," which is a worse diagnostic than services elsewhere in this
corpus (e.g. GCP Cloud Billing's missing-vs-garbage split into 403 vs 400) that
at least separate the two cases.

Not observed, not asserted: behavior with a valid token (none held); rate
limits; the shape of a successful `/api/objects` response.

## Why this is worse than it looks

The `errors[0].code` value is the literal string `"unauthorized"` in both cases
— not `missing_token`/`invalid_token`, not two different values at all. Compare
this cluster's other refusal, HITRAN, which at least routes the two cases
(open wizard steps vs. the gated download step) through visibly different
response shapes (200 HTML vs. 302-to-a-named-path); DISCOS collapses "you never
authenticated" and "you tried to authenticate and failed" into one indistinguishable
JSON:API error object, at any endpoint under `/api/` — the probe above used
`/api/objects`, the collection root, and the same two-request comparison would
be expected to hold for any other `/api/*` path per the shared auth middleware
implied by the identical error text.

## Probes

```
curl -s 'https://discosweb.esoc.esa.int/api/objects'
curl -s -H 'Authorization: <placeholder>' 'https://discosweb.esoc.esa.int/api/objects'
```

How observed: 2026-10-05, direct HTTPS GET with curl at 10:51:16Z UTC against
`discosweb.esoc.esa.int`, two requests (one with no Authorization header, one
with an obviously-invalid placeholder value), no real key ever held or sent for
this host.
