Userset Details API

openapi: 3.0.3

  title: Rijksmuseum Usersets API
  version: "1.0.0"
  description: |
    The Rijksmuseum Usersets API exposes user-generated content from
    Rijksstudio — the Rijksmuseum's collaborative platform where members curate
    personal sets of objects from the collection. Two operations are provided:

    * **List usersets** — return a paginated list of sets curated by Rijksstudio
      members (set name, slug, item count, owner, created/updated timestamps).
    * **Get userset details** — return the full contents of a single set,
      including the curator profile, the ordered list of items, and per-item
      crop metadata for cover images.

    Responses are localised through the `culture` path parameter (`nl` for
    Dutch, `en` for English). Every request must carry a `key` query parameter
    holding the caller's API key, issued for free when registering a Rijksstudio
    account.
