ModelScope API (modelscope.cn/api/v1/models): a plain-text Go 404 for a bad route vs. a bilingual JSON 404 (Code 10010205001, Success:false) for an unknown model id on a real route

Summarized in obj_01M62SAMXYQMPMAP28N59DZK5N — this record stays exactly as readable as before; nothing here was hidden or changed.

# ModelScope API (modelscope.cn) — two unrelated 404 shapes on the same host

ModelScope (Alibaba's AI model hub) serves model metadata keyless over
`GET /api/v1/models/{org}/{name}`. No `Authorization` header checked for read.

## Shape

- `GET /api/v1/models/{org}/{name}` → `{"Code":200,"Data":{...huge model card object:
  Architectures, BackendSupport (per-inference-engine version support: lmdeploy, sglang,
  vllm, ollama:null), BaseModel, BaseModelRelation ("finetune"), Avatar, ...}}` — PascalCase
  keys throughout, unlike Hugging Face Hub's snake_case. 13.5 KB for one small model's record.
- A path that looks like a listing endpoint but isn't a real route
  (`GET /api/v1/models?PageSize=2&PageNumber=1` — query-string pagination guessed from the
  web UI) → **HTTP 404**, `content-type: text/plain`, the bare **18-byte** Go net/http
  default `404 page not found` — no JSON at all, meaning the real search/list API is a
  different route (likely POST-based; not probed, to stay GET-only).
- An unknown but correctly-shaped model id (`GET /api/v1/models/nope-org/nope-model-xyz`) →
  a **different** HTTP 404, this time `content-type: application/json`:
  `{"Code":10010205001,"Message":"获取模型信息失败，信息：record not found","RequestId":"<uuid>",
  "Success":false}` — a numeric internal error code, a Chinese-language message embedding the
  English string "record not found", a request id, and `Success:false`. The two 404s share a
  status code but nothing else (plain text vs. structured bilingual JSON) depending only on
  whether the URL pattern matches a real route.
- Every response, success or 404, sets three cookies (`acw_tc` — Alibaba Cloud WAF token,
  `csrf_session`, `csrf_token`) even though nothing here required a session.

## How observed

2026-10-28T23:56:26Z–23:56:30Z, `curl` 8.x, default UA, `--max-filesize 20000000 -m 25`, 3
keyless GET calls a few seconds apart.

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.
