Wright20 Design Auction Results Scraper

Scrapes Wright auction lot data — hammer prices, designer attribution, provenance, literature citations, condition reports, and catalog images — across all past and upcoming Wright sales. Covers 20th-century design, mid-century modern, Scandinavian design, Italian design, studio furniture, and related categories.

What it does

Wright is the dominant US auction house for 20th-century design. This actor:

1. Walks the Wright sitemap index (600+ per-auction sitemaps) to discover all lot URLs
2. Fetches each lot page and extracts the embedded structured JSON
3. Returns a clean, flat record per lot with full provenance, pricing, and image data

Use cases

• Appraisal research: Cross-reference hammer prices, provenance chains, and exhibition history for attribution and insurance valuation
• Dealer intelligence: Track price history for specific designers (Nelson, Eames, Bertoia, Saarinen, Knoll, Herman Miller) across years
• Academic cataloging: Harvest literature citations and exhibition records for design history research
• Market analytics: Build price indices for MCM design categories, estimate/result ratios, buy-in patterns

Coverage

The actor works across all Wright auction categories visible in the sitemap, including:

• Design (quarterly flagship sales)
• Important Design
• Scandinavian Design
• Machine Age Design 1925-1950
• Essential Design
• American Design
• Italian Design
• Studio Furniture
• Ceramics, glass, art, and specialty sales

Wright's archive spans 25+ years and 50,000+ lots. Set maxItems: 0 to collect the full archive (a complete run takes several hours at the default concurrency).

Technical notes

• Data is embedded as structured JSON in each page (Inertia.js data-page attribute), so extraction is deterministic and fast
• The sitemap index lists upcoming and past auctions — the actor collects both
• hammer_price (sans buyer's premium) equals price_realized divided by approximately 1.27 for standard sales; both fields are provided for flexibility
