Korea's 11번가 as JSON: real prices, stock per option and the 베스트 ranking

- POST/11st/v1/search
- POST/11st/v1/product
- POST/11st/v1/reviews
- POST/11st/v1/ranking

How the 11st (11번가) API works
11st (11번가) is a normal ReefAPI surface — the same four rules that hold for every other engine on the key.
No OAuth app, no request signing, no per-site account. One key covers all 491 engines.
Every route is a POST with a JSON body. Parameters are validated against the published schema before anything is charged.
Credits, not seats. Failed and blocked calls are never charged, and cache hits cost nothing.
One envelope everywhere. meta carries latency_ms, record_count and the endpoint that answered.
From a keyword to the cheapest real offer and what buyers say
Search, open the products that matter, then read their reviews.
About 84 organic rows sorted by price with sell and discounted price, seller, shipping fee and rating; sponsored rows separately in ads; page up to 24.
Sell, discounted, coupon and maximum-benefit price, stock per option, seller satisfaction and response rate, courier, fee and arrival promise.
10 reviews per page with rating, text, option bought and photo or video flags; total plus the positive and negative split.
A price and stock view of any product on 11번가, comparable with Coupang and Gmarket, with buyer feedback attached.

}What an 11st field actually contains
Fields that read differently from how they look. Every row was measured against live 11st answers on 2026-10-14.
| Field | What it holds |
|---|---|
| sell_price, final_price | Two prices in won. sell_price is 11st's 판매가; final_price is the price the page shows after the seller's and 11st's instant discounts. On 10 of 10 products the search row and the product page agreed on both, and the ranking card agreed with the product page on 6 of 6. |
| coupon_price | Set only when a coupon actually lowers the price. Many products show a '쿠폰보기' button whose block repeats the sell price with a zero discount; that is not a coupon price and is returned as null. |
| max_benefit_price, price_breakdown | 11st's own 할인혜택가: the estimate with every visible benefit applied, with the lines it adds up (sell price, instant discount, multi-buy discount). Null when 11st shows no such estimate for the product. |
| review_count | The search card, the product page and the catalogue-wide figure in the page's structured data can differ: one ramen listing had 16,935, 13,110 and 78,911. product returns the listing's own count, which matches the total of the reviews call. |
| options[].options[].stock_qty | Stock per option as 11st publishes it. Options come in two levels; the second level's stock belongs to the first-level option that is selected by default. A sold-out option stays in the list with sold_out true and stock 0. |
| sales_count, sales_badge | sales_count is the plain counter (1,018). Some cards print a rounded badge instead, such as 구매 1천+ (1,000 or more); sales_badge_min turns that into a number and keeps the original text. |
| product_id | 11st's product number, the one in 11st.co.kr/products/<id>, as a string. Every search and ranking row carries it and product accepts it unchanged: 10 of 10 round trips matched. |
Prices are 11st Korea's prices in won; the same product and search returned identical prices, stock, delivery fee and arrival date from a Korean and a non-Korean network. Member (11번가플러스, T멤버십) and card-conditional prices are only shown to logged-in buyers and are not returned.

The questions people actually ask before wiring up 11st (11번가).
Get a free key →Do I need an 11st account?▾
No. Everything is read logged out, and you call reefapi.com from anywhere.
Are sponsored products mixed into the results?▾
No. 11st places sponsored rows inside its result page; they are returned in a separate ads list with the slot they came from. On the nike page 1 there were 62 organic and 72 sponsored rows.
Which search filters work?▾
Seven sorts, price range, free shipping, official and department stores, used, overseas direct, no overseas direct, and a top category. Each was checked against the unfiltered count in the same run: 운동화 2,232,130 → 30,000 to 50,000 won 348,065, free shipping 1,557,478, official stores 2,063, used 8,961, overseas direct 353,249, sports category 939,072.
How deep can I page a search?▾
24 pages. 11st repeats page 24 for any higher page number, so pages above 24 are refused instead of billing you for duplicate rows.
Is stock per option available?▾
Yes, from product: every option has its own stock count and sold-out flag, plus the stock of the default option. One cap had six options, one of them sold out with stock 0.
Can I get the 11번가 베스트 ranking?▾
Yes. ranking returns the top 40 overall, for any of 15 category groups or 182 sub-categories, and for men or women shoppers. Each row has rank, struck-through price, price, discount, seller and likes.
Is this the same as the Gmarket or Coupang API?▾
No. Gmarket and Coupang are separate Korean marketplaces with their own catalogues and sellers; this API reads 11st only. Field names follow the same pattern across the three, so rows can be compared side by side.
What is the 11st (11번가) API?▾
11st (11번가) API is a ReefAPI endpoint group for korea's 11번가 marketplace: search with sponsored rows apart, full products with stock per option, reviews and the 베스트 ranking. It returns live JSON through POST requests under /11st/v1.
Is the 11st (11번가) API free to try?▾
Yes. ReefAPI starts with 1,000 free credits, no card required. 11st (11번가) calls use the same shared credit balance as every other ReefAPI engine.
Do I need a 11st (11번가) login or account?▾
No login to 11st (11번가) is needed for the API response. You call ReefAPI with your x-api-key header, and the playground can run live examples before you create a production key.
How fresh is the 11st (11번가) data?▾
The page example is captured from a live search call, and production requests fetch live data through ReefAPI rather than a static sample.
How many credits does the 11st (11번가) API use?▾
11st (11번가) actions currently cost 2-3 credits per successful call. Failed or blocked calls are free. All APIs draw from one credit pool.
Can I call 11st (11번가) from an AI assistant or MCP client?▾
Yes. Connect ReefAPI once through MCP and your assistant can call 11st actions with the same key, credit pool and JSON envelope used by normal REST requests.
Is the 11st (11번가) API a 11st (11번가) scraper?▾
It is the managed alternative to a DIY 11st (11번가) scraper. Instead of building and maintaining your own scraper — proxies, headless browsers, captcha and constant breakage — you call one ReefAPI endpoint and get the same korea's 11번가 marketplace: search with sponsored rows apart, full products with stock per option, reviews and the 베스트 ranking back as clean JSON.
231 E-commerce & Marketplaces APIs on the same key
One key, one credit pool, one response envelope. If you are pulling 11st (11번가), you are one call away from the rest of the category — no second contract, no second integration.
Need something this API does not do?
Name the endpoint, the field, or a source we do not carry yet. We ship new APIs every week and you would be first to get the key. Real people read every message and reply the same day.
Try it on your own data before you pay anything
The call above is the real endpoint, not a recording. A free key gives you 1,000 credits, the other 490 APIs, and the same envelope everywhere.
Endpoints, parameters and credit costs on this page are read from the live catalog and cannot drift from what the API accepts. Field notes were captured on 2026-10-14.
