11st (11번가) product data API

ShopAPIS extracts structured product data from 11st (11번가) — South Korea’s SK Square-owned open marketplace — and returns it as clean JSON. For any 11st listing you get title, current and original price, Shooting Delivery (슈팅배송) eligibility, Amazon Global Store flag, seller name and rating, option matrix, category path, rating, review count and the image gallery.

11st is one of South Korea’s long-standing open marketplaces, owned by SK Square (Inside Retail Asia — Korea e-commerce shakeout ). While the market consolidates toward the Coupang/Naver duopoly, 11st remains a meaningful cross-seller catalog in a ~$215B online market and operates an Amazon Global Store giving it a cross-border product surface peers lack.

Why 11st data is hard to get

11st has no open public catalog API and applies standard Korean-marketplace bot defenses. Prices, member coupons, Shooting Delivery flags and option pricing render client-side and depend on login state; the platform rate-limits and fingerprints clients. Listings are Korean-language with seller-defined option trees, and Amazon Global Store items carry cross-border pricing and import handling. ShopAPIS uses in-region clients and normalizes the option matrix, delivery flags and seller fields into a single schema.

Data fields returned

• Identity — product number, title, brand, category path
• Price — current price, original price, discount %, currency (KRW)
• Delivery — Shooting Delivery flag, shipping cost, delivery estimate
• Sourcing — Amazon Global Store / cross-border flag
• Seller — seller/shop name, seller rating
• Options — option/variant matrix, per-option price and stock
• Reviews — count, average rating
• Media — image gallery
