Endpoints 6

• GET?f=jsonDirectory: version, folders and services (name + type).
• GET/{dienst}/FeatureServer?f=jsonService: layers and tables (id, name, group layer or not), maxRecordCount, capabilities, projection, description.
• GET/{dienst}/FeatureServer/{laag}?f=jsonLayer: fields (name, type, alias, length), geometry type, maxRecordCount, supportedQueryFormats and advancedQueryCapabilities (pagination, statistics, orderBy, distinct).
• GET/{dienst}/FeatureServer/{laag}/queryQuery features with a where clause or spatial filter; also count (returnCountOnly) and group (outStatistics). Response in JSON, GeoJSON or PBF.
• GET/{dienst}/FeatureServer/legend?f=jsonLegend per layer: labels and symbols (PNG as base64).
• GET/{dienst}/FeatureServer/{laag}/query?…&f=pbfSame query as protobuf (application/x-protobuf): compact for large layers.

The APIs of this source 1 · from the provider's documentation from the description

Filtering platform

SQL-like where clause on the layer's fields, plus an optional spatial filter (geometry). Group and count with outStatistics.

Parameters 13

Fields of the example layer 10 · Suppleties_v2/FeatureServer/11 (537 suppleties)

Limits and pitfalls

• At most 2.000 features per response (the layer's maxRecordCount; varies per layer, see /{layer}?f=json). If there are more, the response has exceededTransferLimit: true: fetch the rest with resultOffset and resultRecordCount. tested
• No key and no documented rate limit. Take it easy (a few requests per second) and prefer statistics or counts over fetching all features. experience
• Unlike the provincial servers, every layer has editingInfo.lastEditDate and dataLastEditDate in milliseconds (Suppleties: 29 April 2026, Inweva2025: 30 March 2026). Useful for tracking changes. tested
• Errors come back with HTTP 200 and a JSON object {"error": {"code": 400, …}} ('Failed to execute query.' for an unknown field in where). Always check for an error field, not just the status code. tested
• The directory has no folders: all 473 services are in the root. 105 names end in _view (read-only copy of another service); use the source service. tested
• The only WFSServer in the list (TenT_Roads_NL) returns 'Unsupported service type: WFSServer' via the REST path. There is no WMS and no export: these are hosted FeatureServers. tested
• Layers are in RD (EPSG:28992); request outSR=4326 for degrees. GeoJSON responses include a crs block. tested
• Many RWS items in the ArcGIS Online search index point to geo.rijkswaterstaat.nl (another server), not to these services. experience
