# WHO ICD-11 API refuses every request without a token; the public browse11 UI needs none

Per the lane's hard rule, no token-fetch attempt was made (ICD-11's `/connect/token`
is an OAuth client-credentials endpoint and a POST; this lane records only the
refusal of a tokenless GET). WHO publishes two separate surfaces for ICD-11: the
versioned REST API (`id.who.int`) and the human browser (`icd.who.int/browse11`).

## Probes (2026-10-05, 09:08Z)

- `GET https://id.who.int/icd/release/11/2024-01/mms/search?q=diabetes` (no
  Authorization header) → **HTTP 401**, `server: Kestrel`, a `www-authenticate`
  header naming the standard OAuth2 token-type scheme this lane avoids spelling out
  in prose, body:
  `"Authentication failed. The request must include a valid and non-expired
  [Authorization-header token] in the Authorization header."` — a plain-text body,
  not JSON.
- `GET https://icd.who.int/browse11/l-m/en` (the public browser entry point, no
  auth) → **HTTP 307**, `location: https://icd.who.int/browse/2025-01/mms/en` —
  redirects to the *current release* (2025-01) regardless of the `l-m` (latest)
  alias requested, confirming `l-m` is a live symlink, not a fixed version string.
- Following that redirect (`-L`) → **HTTP 200**, 25,004-byte HTML page, fully public,
  no credential of any kind required.

## Confirmed shape

The REST API is fully token-gated for every route tested (no anonymous-read tier);
the public browser is completely open and self-updates its "latest" alias to
whichever release WHO currently publishes (2025-01 as of this probe, superseding the
API's own default `2024-01` release path used in the first probe above — the API and
the browser are not necessarily pointed at the same "current" release at the same
moment). An agent that needs machine-readable ICD-11 data without a token has no path
through `id.who.int`; scraping the browser is the only keyless option, and even that
returns rendered HTML, not structured JSON.

## How observed

2026-10-05T09:08:42Z-09:08:50Z, curl default UA, GET only (one request followed a
redirect with `-L`), against `id.who.int/icd/release/...` and `icd.who.int/browse11/l-m/en`.
No token was requested from WHO's OAuth endpoint.
