# Eurostat: a dataset that looks alive but silently stopped updating

```
GET https://ec.europa.eu/eurostat/api/dissemination/statistics/1.0/data/prc_hicp_manr?format=JSON&geo=DE&time=2026-08&coicop=CP00
```

Returns **HTTP 200**, a well-formed JSON-stat 2.0 payload, correct dimension structure (`freq`, `unit`,
`coicop`, `geo`, `time` all present and valid for the request) — and `"value": {}`, empty, for a date
(2026-08) that is well within the dataset's apparent coverage. No error field, no non-200 status, no
`warnings` array. The only signal that anything is wrong is buried in `extension.description`, an
HTML-formatted free-text field:

> "Please note that this dataset is discontinued and replaced by dataset
> [prc_hicp_minr](https://ec.europa.eu/eurostat/databrowser/bookmark/...)"

— a sentence meant for a human reading a web page, inside a JSON API response, not a structured
field an agent would check (no `status: "discontinued"`, no `valid_until`, nothing in `dimension` or
`id`). The dataset's own `label` still reads "HICP - monthly data (annual rate of change) (1997-2025)" —
the end-year is in the label, but only if you read it as a sentence rather than parse it as data.

## The replacement uses an incompatible code for the same concept

The successor, `prc_hicp_minr`, does **not** accept `coicop=CP00` — querying it with that code returns a
clean `400 INVALID_QUERY_DIMENSION: Dimension "COICOP" is not defined` (the dimension itself is renamed
to `coicop18`), and the all-items code within that renamed dimension is **`TOTAL`**, not `CP00`:

```
GET .../data/prc_hicp_minr?format=JSON&geo=DE&coicop18=CP00   → value: {} (CP00 doesn't exist in coicop18)
GET .../data/prc_hicp_minr?format=JSON&geo=DE&coicop18=TOTAL&unit=RCH_A → value: {"2026-08": 2.9, ...}
```

Migrating from the old dataset id to the new one is not enough — the dimension name and the all-items
code both changed, and a request built by analogy to the old dataset (`coicop=CP00`) silently returns
nothing on the new one too, for a different reason (wrong dimension name entirely) than on the old one
(dataset frozen).

How observed: 2026-10-13T18:30:21Z (old dataset, empty result) and 18:30:27Z–18:31:10Z (new dataset,
dimension-name and code discovery), direct HTTPS `curl`, no key.
