Data sources

Data sources represent the raw source configurations in Nexus. Unlike data subscriptions (which are world-specific), data sources are shared across worlds. To get an overview of all data sources available to your organization run:

curl "https://nexus.stellaspark.com/api/v1/data_sources/?token={web_api_token}"

It is also possible to filter by world and dc_id (data connection ID). For example:

curl "https://nexus.stellaspark.com/api/v1/data_sources/?token={web_api_token}&dc_id=6"

This returns for example:

[
    {
        "name": "Klimatologie - Daggegevens meteostations",
        "owner": "KNMI",
        "description": "This data source contains daily meteorological observations from the KNMI automatic weather stations (AWS) across the Netherlands. It holds 
        measurements including precipitation, reference evapotranspiration, relative humidity, incoming solar radiation, maximum and mean air temperature, wind 
        direction, and wind speed metrics. Each measurement series is linked to its corresponding station, covering both recent and historical periods.",
        "private": false,
        "uploadable": false,
        "endpoint": "https://www.daggegevens.knmi.nl",
        "harvest_last_success": "2026-02-03T12:01:54Z"
    }
]

The description field is localized, meaning it is translated into the language of your world's locale. You can override it with the locale query parameter (options: de_DE, en_IE, en_US, es_ES, fr_FR, it_IT, ja_JP, nl_NL, pt_BR, ru_RU, zh_CN).

Public data sources can also be accessed without a token:

curl "https://nexus.stellaspark.com/api/v1/data_sources/"

Note

Anonymous access only returns public data sources and does not support filters (world, dc_id). Attempting to filter without a token will return a 403 error.

Definition of the fields is as described in the table below.

Field	Meaning
name	Name of the data source
owner	Organization owning/maintaining the data source
description	Description of the data source (localized)
private	Whether the data source is private (true) or public (false)
uploadable	Whether users can upload files to this data source
endpoint	Base URL that Nexus uses to harvest the data from
harvest_last_success	Timestamp when the data was last successfully harvested
