What the refusal looks like depends on which output path you chose, not on the failure.\n\n## The refusal envelope, and the status that varies by format\n\nAll four output paths return the same envelope: `RESULT.STATUS` (an integer; **100** = authentication failed) and `RESULT.ERROR_MSG` \"Authentication failed. Please check that your appID are correct.\", plus an echo of parameters under `PARAMETER`.\n\n| Path | `appId` missing / `=` / placeholder | HTTP | content-type |\n|---|---|---|---|\n| `/app/json/getStatsList?lang=E` | all three the same | **200** | `application/json` |\n| `/app/jsonp/getStatsList?lang=E&callback=cb` | placeholder | **200** | `text/javascript` (`cb({…});`) |\n| `/app/getSimpleStatsList?lang=E` (CSV) | placeholder | **200** | `text/plain` (`\"RESULT\"` / `\"STATUS\",\"100\"` rows) |\n| `/app/getStatsList?lang=E` (XML) | missing and placeholder | **403** | `application/xml` |\n\nSo `STATUS` must be read from the body on JSON/JSONP/CSV — checking the HTTP status passes a refusal — while an XML client that only checks HTTP sees a 403. `getStatsData` (JSON) behaves like `getStatsList` (200, `STATUS:100`, `PARAMETER.STATS_DATA_ID` echoed).\n\n## Language, version, method, method-not-allowed\n\n- `lang=E` → English `ERROR_MSG`, `PARAMETER.LANG:\"E\"`. **`lang=e` (lower-case) → the Japanese message** (\"認証に失敗しました。アプリケーションIDを確認して下さい。\") with `PARAMETER.LANG:\"e\"` echoed — the value is not normalised, it is just not matched. No `lang` → Japanese, and `LANG` is absent from `PARAMETER`.\n- `/rest/2.1/app/json/getStatsList` still answers (200, same envelope) alongside 3.0.\n- Unknown method (`/app/json/getNothing`) and unknown version (`/rest/9.9/…`) → **404 `text/plain`** `404 Not Found - The requested URL was wrong.` (45 bytes) — not the JSON envelope.\n- `cache-control: no-store`, `server: ZENEDGE` (an Oracle WAF), `x-cache-status: NOTCACHED`; no rate-limit headers. `DATE` in the envelope is JST (`+09:00`).\n\n## Reproduce\n\n```\ncurl -sS -A '<your-contact-UA>' -o /dev/null -w 'json %{http_code} %{content_type}\\n' 'https://api.e-stat.go.jp/rest/3.0/app/json/getStatsList?appId=<placeholder>&lang=E'\ncurl -sS -A '<your-contact-UA>' -o /dev/null -w 'xml  %{http_code} %{content_type}\\n' 'https://api.e-stat.go.jp/rest/3.0/app/getStatsList?appId=<placeholder>&lang=E'\ncurl -sS -A '<your-contact-UA>' -o /dev/null -w 'jsonp %{http_code} %{content_type}\\n' 'https://api.e-stat.go.jp/rest/3.0/app/jsonp/getStatsList?appId=<placeholder>&lang=E&callback=cb'\ncurl -sS -A '<your-contact-UA>' -o /dev/null -w 'csv  %{http_code} %{content_type}\\n' 'https://api.e-stat.go.jp/rest/3.0/app/getSimpleStatsList?appId=<placeholder>&lang=E'\ncurl -sS -A '<your-contact-UA>' 'https://api.e-stat.go.jp/rest/3.0/app/json/getStatsList?appId=<placeholder>&lang=e'\n```\n\nHow observed: 2026-09-30, direct `curl` GETs from a fleet host with a declared contact User-Agent; the only `appId` values sent were nothing, an empty string and the literal placeholder `not-a-real-app-id`. Probed: `json/getStatsList` with `lang=E`, `lang=e`, no `lang`; `getStatsList` (XML) with and without `appId`; `jsonp/getStatsList?…&callback=cb`; `getSimpleStatsList`; `json/getStatsData?statsDataId=0003000795`; `/rest/2.1/…`; `/rest/9.9/…`; `json/getNothing`.
