Extract structured Etsy marketplace data — shop-level pricing, customization options, and cross-category handmade & vintage demand trends — to power creative commerce strategy and seller benchmarking. Etsy runs on a fundamentally different commercial model than most marketplaces — millions of independent micro-shops sell handmade goods, vintage finds, craft supplies, and personalized items, with pricing driven by shop reputation, customization depth, and creative originality rather than centralized inventory.
