What is the CBS StatLine (Netherlands) API?

CBS, Statistics Netherlands, publishes its StatLine tables through a free OData API with no key. Each table has a code such as 83625NED, and its `TypedDataSet` endpoint returns typed rows that can be filtered, projected and paged entirely server-side using standard OData query options.

Using OData instead of a bespoke query language is a real advantage: `$top`, `$skip`, `$filter`, `$select` and `$orderby` all behave the way they do in any OData client, and existing tooling in .NET, Python and JavaScript works without a custom adapter. Each table exposes several endpoints — `TypedDataSet` for values with proper types, `UntypedDataSet` for raw codes, plus `TableInfos` and one endpoint per dimension holding the code-to-label mappings.

The catch is that dimension values are codes with significant whitespace. A region arrives as `"NL01 "` — padded to a fixed width — and a period as `"1995JJ00"`, where `JJ` marks an annual figure and the trailing digits identify the sub-period. Trim before comparing, and join against the dimension endpoints to turn those codes into names. Table codes ending `NED` are Dutch-language; the `ENG` variants carry English labels for a subset of tables.

How to use the CBS StatLine (Netherlands) API

Every request below was executed against the live API on 21 Aug 2026, and the response shown is the real body it returned — not an illustration.

1. Fetch a row from a CBS StatLine table

GET https://opendata.cbs.nl/ODataApi/odata/83625NED/TypedDataSet?$top=1&$format=json

curl

curl 'https://opendata.cbs.nl/ODataApi/odata/83625NED/TypedDataSet?$top=1&$format=json'

JavaScript (fetch)

const res = await fetch("https://opendata.cbs.nl/ODataApi/odata/83625NED/TypedDataSet?$top=1&$format=json");
if (!res.ok) throw new Error(`Request failed: ${res.status}`);
const data = await res.json();
console.log(data);

Python (requests)

import requests

res = requests.get("https://opendata.cbs.nl/ODataApi/odata/83625NED/TypedDataSet?$top=1&$format=json", timeout=20)
res.raise_for_status()
print(res.json())

Response — HTTP 200

{
  "odata.metadata": "https://opendata.cbs.nl/ODataApi/OData/83625NED/$metadata#Cbs.OData.WebAPI.TypedDataSet",
  "value": [
    {
      "ID": 0,
      "RegioS": "NL01  ",

      "GemiddeldeVerkoopprijs_1": 93750
    }
  ]
}

Parameters

Parameter	Type	Required	Description
`{table}`	path	Required	StatLine table code, for example `83625NED` for average house sale prices. `83625NED`
`$top`	query	Optional	Rows to return. `1`
`$skip`	query	Optional	Rows to skip, for pagination. `100`
`$filter`	query	Optional	OData filter expression over dimension codes. `Perioden eq '2023JJ00'`
`$select`	query	Optional	Columns to return. `RegioS,Perioden,GemiddeldeVerkoopprijs_1`
`$format`	query	Optional	`json` for JSON output; the service otherwise negotiates. `json`

Response fields

odata.metadatastring: URI of the table's metadata document, useful for discovering column names and types.
valuearray: The data rows.
value[].IDinteger: Row index within the table. Not a business key — it shifts when the table is republished.
value[].RegioSstring: Region code, space-padded to a fixed width such as `"NL01 "`. Trim before comparing.
value[].Periodenstring: Period code such as `1995JJ00`; `JJ` marks an annual value, `KW` a quarter, `MM` a month.
value[].<Measure>_nnumber: Measure columns are suffixed with a numeric index, for example `GemiddeldeVerkoopprijs_1`.

Common errors and how to fix them

Filter matches nothing

Dimension codes are space-padded.

Fix: Compare against the exact padded value, or use `startswith()` in the filter rather than equality.

404 on the table code

Wrong code, or the table has been withdrawn.

Fix: Check the code in StatLine; `NED` suffixes are Dutch tables, `ENG` are the English-labelled subset.

Columns are unreadable codes

Dimension values are codes, not labels.

Fix: Fetch the dimension endpoints, such as `/RegioS`, and join on the code to get names.

Row IDs shift between runs

`ID` is a positional index, not a key.

Fix: Build your own key from the dimension columns instead of persisting `ID`.

CBS StatLine (Netherlands) API — frequently asked questions

Is the CBS open data API free?

Yes, no key and no registration. Statistics Netherlands publishes all StatLine tables openly, and reuse including commercial use is allowed with attribution.

How do I find a table code?

Browse StatLine on the CBS website; the code appears in the table's URL and metadata — for example 83625NED for average house sale prices. Codes ending NED are Dutch, ENG are the English-labelled tables.

What does 1995JJ00 mean?

It is a CBS period code: the year followed by a type marker and sub-period. `JJ` indicates an annual figure, `KW` a quarter and `MM` a month, so `1995JJ00` is the whole of 1995.

Should I use the v3 or v4 API?

The v3 ODataApi documented here is stable and covers every StatLine table. The newer v4 service at datasets.cbs.nl offers the same data in a different shape; pick one and stay on it, since the response structures differ.
