## Probes

```
GET https://api.thingiverse.com/things/1                              (no Authorization header)
GET https://api.thingiverse.com/things/1?access_token=<placeholder>
```

## Observed

Both HTTP 401, `www-authenticate: Bearer V1`, `access-control-allow-methods: GET, PUT, POST,
DELETE, PATCH, OPTIONS` (CORS wide open even on the 401), served via Cloudflare with a fresh
`PHPSESSID` + `__cf_bm` cookie pair set on every anonymous call. The bodies differ:

- No token: `{"error":"Unauthorized access. No authentication was provided.","code":401,"type":"NO_TOKEN_PROVIDED"}`
- Garbage token: `{"error":"Unauthorized access. You must be logged in to perform this action.","code":401,"type":"INVALID_ACCESS_TOKEN"}`

## Conclusion

The redundant `code: 401` field inside the JSON body matches the HTTP status exactly (no extra
information there), but the `type` enum (`NO_TOKEN_PROVIDED` vs `INVALID_ACCESS_TOKEN`) is a
genuine, documented-feeling distinction most of this corpus's other OAuth/token-gated peers
don't offer — contrast Freesound in this same lane, which collapses both cases to the bare DRF
`"Invalid token"`/`"not provided"` strings with no enum, or Square (corpus, prior lane), which
returns byte-identical bodies for both cases. Every anonymous GET to Thingiverse also sets two
session cookies (`PHPSESSID`, `__cf_bm`) even though the endpoint requires OAuth2 — the PHP
session layer runs ahead of, and independent of, the auth check; a stateless client ignoring
`Set-Cookie` loses nothing, since neither cookie is required on the retry with a real token
(OAuth2 bearer tokens are stateless by design), but it does mean every single unauthenticated
probe against this API leaves a fresh anonymous session server-side. The
`content-security-policy` header on this bare JSON 401 also names three allowed frame
ancestors (`*.thingiverse.com`, `*.onshape.com`, `*.thingiverse.local`) — Onshape's presence
there, even on an anonymous error response, is a visible trace of shared infrastructure between
the two products.

How observed: 2026-10-05T10:51:54Z, curl GET/HEAD, UA `pwx-scout/1.0`, `--max-filesize 20000000 -m 60`.
