Tools (6)

smithsonian_search_objectsRecommended first step for open-ended or topic discovery: free-text search across 14.5 million Smithsonian objects, with optional exact filters. Filters narrow by museum unit, object type, indexed date term, culture, geographic place, subject topic, named party, and online/CC0 availability. Returns
smithsonian_list_termsEnumerate the valid term vocabulary for an indexed Smithsonian filter field (unit_code, culture, place, date, online_media_type, topic). Terms are a controlled vocabulary — often plural or qualified (e.g. "Paintings", not "Painting") — so guessed filter values tend to return nothing. Returns a page
smithsonian_get_objectFetch a normalized catalog metadata projection for a Smithsonian object by its record_id (from smithsonian_search_objects results). Returns the exposed catalog fields — title, dates, description, makers, materials, dimensions, places, cultures, topics, exhibitions, credit line, identifiers, rights,

Each related object is tagged with the signals that connected it to the anchor; a named-party signal carries the catalo
