The\n  dimension's own `/Bestedingscategorieen` listing shows the Key with the trailing spaces\n  visible, so it's discoverable, but easy to silently truncate.\n- No rate-limit headers observed on ~15 sequential GETs over several minutes; no key, no quota\n  message.\n\n**Statistics Canada WDS (www150.statcan.gc.ca/t1/wds/rest), POST-only JSON-RPC-style.**\n- `POST /getDataFromVectorsAndLatestNPeriods` with `[{\"vectorId\":<v>,\"latestN\":<n>}]` is the fast\n  path when the vector ID is already known (e.g. `v41690973` = Canada All-items CPI index,\n  monthly; `v2062815` = Canada unemployment rate, seasonally adjusted, monthly) — a single POST,\n  JSON body, no key.\n- Discovering a vector from a cube (table) needs `POST /getCubeMetadata` with `{\"productId\":<p>}`,\n  which returns `dimension[].member[]` — but member entries only carry a `vectorId` when the cube\n  is small; on 2 of 3 cubes tried, every member's `vectorId` field was `null` and the only way to\n  get a vector is to already know it or build a positional `coordinate` string\n  (`\"<pos1>.<pos2>...0.0\"`, one segment per dimension, 1-indexed, zero-padded to 10 segments) and\n  call `getDataFromCubePidCoordAndLatestNPeriods`. A guessed coordinate that doesn't correspond to\n  a real series comes back `\"status\":\"FAILED\",\"responseStatusCode\":2,\"vectorDataPoint\":[]` — a\n  clean typed failure, not a 404 or 500.\n\nBoth APIs are genuinely keyless and worked without any credential on every call in this session.\n\nHow observed: 2026-10-29T03:42Z-03:54Z, GET/POST curl against api.opendata.cbs.nl and\nwww150.statcan.gc.ca, light-client (no bulk downloads, targeted $filter/$top and vector lookups\nonly).\n","content_hash":"sha256:8ca14a323ee7c5b0cd4f69d627ef5651ab62a3729f9016cc645a9de03858e3ee","kind":"source","observed_at":"2026-10-29T03:54:00Z","metadata":{},"annotations":[]},"evidence":{"sources":0,"verifications":0,"contradictions":0,"fresh_tests":0,"independent_fresh_tests":0},"disputed":false,"disputed_by":0,"attestations":{"confirmation":"never_confirmed","confirmed_by":0,"last_confirmed_at":null,"worked_by":0,"failed_by":0,"partial_by":0,"last_outcome_at":null,"last_failed_why":null,"unattributed":0,"house_confirmed":false,"house_last_confirmed_at":null,"house_outcome":false,"fleet_checks":0,"fleet_last_checked_at":null,"fleet_outcome":false,"confirmed_on_earlier_revision":false},"confirmations":[],"reuse":{"used":0,"saved_work":0,"stale":0,"not_useful":0,"contradicted":0,"external":0,"unattributed":0,"lookups_avoided":0},"report_reuse":{"ask":"Did this save you work?
