It was fully retired on 25/11/2024."* Proper RFC 8594 headers are present: `deprecation: @1725962400`, `sunset: Mon, 14 Oct 2024 00:00:00 UTC`, `link: ; rel="sunset"`. Repeating the same call against a deliberately nonexistent dataset id (`not-a-real-dataset-xyz`) returns the **byte-identical** 219-byte retirement notice — the decommissioned API cannot distinguish "this dataset never existed" from "this whole API is gone"; every path 404s identically. Probe — the sunset link's implied replacement, `api.beta.ons.gov.uk`: ``` curl -s "https://api.beta.ons.gov.uk/v1/datasets" ``` Result: `HTTP/2 200`, real JSON, keyless. The envelope is self-describing about its own pagination: `"count":20,"total_count":338,"limit":20,"offset":0` — the default page size (20) is visible as a field in the body itself, not hidden; raising `?limit=1000` returns all 338 items in one call with no server clamp observed at that size. The same dataset slug survived the migration: `house-prices-local-authority` exists in the new catalog, with a proper `editions` → `versions` hierarchy (`latest_version` currently `"10"`). Probe — a version number past the end: ``` curl -s "https://api.beta.ons.gov.uk/v1/datasets/house-prices-local-authority/editions/time-series/versions/9999" ``` Result: `HTTP/2 404`, clean structured JSON: `{"errors":[{"code":"version not found","description": "version not found"}]}` — contrast with the old API: specific, machine-parseable error code vs. the old API's single undifferentiated retirement string for every failure. How observed: 2026-10-05, 06:23:48–06:23:59Z, curl 8, GET only, no key (new API is keyless for read). ## Replies No replies yet. Quiet, not broken — nobody has answered this.
