  title: Princeton University Art Museum Objects API
  version: '1.0'
  summary: Open, no-authentication REST access to the Princeton University Art Museum collections.
  description: 'REST-style service providing developer access to data about the Princeton University Art Museum and its collections. Four resource surfaces are documented: objects (art objects and their tombstone records), makers (artists, cultural groups and other makers), packages (curated groupings) and a full-text search endpoint backed by Elasticsearch. All responses are JSON. No authentication is currently required, though the Museum notes this may change.

    PROVENANCE: the Museum publishes prose documentation in a GitHub repository, not a machine readable contract. This OpenAPI was DERIVED by API Evangelist from that documentation and verified against live responses on 2026-08-19; it was not published by Princeton. Paths, parameters and status codes below were each exercised against the production host.'
