POST /search - Search Artworks

Search the collection using text queries with optional filters.

curl -X POST https://museum-semantic-search.vercel.app/api/mcp/search \
  -H "Content-Type: application/json" \
  -d '{
    "query": "person with a dog",
    "mode": "semantic",
    "limit": 10
  }'

Request body:

{
  "query": "string (required)",
  "mode": "hybrid | semantic | keyword",
  "detail": "minimal | standard | full",
  "filters": {
    "artistName": "string (fuzzy matched)",
    "yearStart": 1800,
    "yearEnd": 1900,
    "department": "string (exact match)",
    "culture": "string (exact match)",
    "classification": "string (exact match)",
    "tags": ["string (exact match)"],
    "medium": "string (fuzzy matched)",
    "country": "string (exact match)",
    "onView": true,
    "isPublicDomain": true
  },
  "limit": 10,
  "offset": 0
}

Mode selection:

"hybrid" (default, recommended): Combines keyword + semantic search. Best for most queries.
"semantic": For purely conceptual/descriptive queries like "lonely figure in nature", "woman looking in mirror", "stormy seascape"
"keyword": For exact matches like artist names or specific titles

Detail levels:

"minimal": Just id, score, title, artist, date (fastest)
"standard" (default): + medium, classification, department, tags, culture, image_url, source_url, alt_text (concise AI description)
"full": + long_description (detailed AI description), similar_artworks, dimensions, etc. Use when you need to verify semantic content.

Workflow

Step 1: Discover the Collection

Call GET /filters first to see available departments, cultures, mediums, tags, and date ranges. Use search mode to find specific filter values.

Step 2: Search

Use POST /search - hybrid mode (default) works well for most queries.

Step 3: Get Details

Call GET /artwork/{id} on interesting results, or use detail: "full" in search to get complete details inline.

Step 4: Explore

Use GET /similar/{id} to discover related works.

Example Queries

Query	Recommended Mode	Why
"person with a dog"	hybrid (default)	Works well for most queries
"woman looking in mirror"	semantic	Purely conceptual description
"stormy seascape"	hybrid	Mood-based but may match titles
"Madonna and child"	hybrid	Common in artwork titles
"Rembrandt self portrait"	hybrid	Artist name + description
"paintings from 1880s"	hybrid + filters	Use yearStart/yearEnd filters

Tips

The collection is primarily European and American paintings from the Met Museum
AI-generated descriptions enable finding artworks by what's depicted, not just metadata
Use source_url to link users to the official Met Museum page
Pagination: when has_more is true, increase offset to get more results
For similar artworks: "precomputed" gives the best quality with explanations; "embedding" is faster
No authentication required - the API is publicly accessible
