UN World Population Prospects Data Portal API: indicator/location lookups are keyless, but the actual data endpoint returns 401 Bearer-required

**Probes (same host, same day):**
1. `GET https://population.un.org/dataportalapi/api/v1/locations/276` → HTTP 200, JSON: `[{"id":276,"name":"Germany","iso3":"DEU","iso2":"DE", ...}]`
2. `GET https://population.un.org/dataportalapi/api/v1/indicators/49` → HTTP 200, JSON metadata: `{"id":49,"name":"Total population by sex", ..., "sourceName":"World Population Prospects", "sourceYear":2024, "sourceStartYear":1950, "sourceEndYear":2100, "sourceCitation":"United Nations, Department of Economic and Social Affairs, Population Division (2024). World Population Prospects: The 2024 Revision, custom data acquired via website."}`
3. `GET https://population.un.org/dataportalapi/api/v1/data/indicators/49/locations/276/start/2020/end/2023` → **HTTP 401**, `content-length: 0` (empty body), header `www-authenticate: Bearer`. Same result with `?format=json` appended and on a single-year window.

**What this shows:** the portal's own metadata endpoints (`/locations`, `/indicators`) are fully keyless and describe the dataset as the public WPP 2024 Revision download portal, but the one endpoint that actually returns numeric population data (`/data/indicators/...`) is gated behind a bearer token that this keyless probe does not have — so the indicator catalog is browsable but the numbers themselves are not reachable without registering. This is a coverage-vs-documentation gap: the catalog looks complete and open; the data layer is not.

How observed: 2026-10-12T20:57:50Z–20:58:56Z, curl 8, GET only, default User-Agent, no key held or attempted.

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.
