Korea Tender Winners (낙찰자 현황) — Company, Amount, Award Rate

Korea's public sector awards roughly 1,200 contracts a day. This Actor returns each one as a clean record: which company won, its business registration number, the amount in KRW, the award rate, how many firms bid, and where the winner is based.

The government publishes all of it — in Korean, across four separate endpoints, with the numbers arriving as strings. This Actor merges the four, translates the schema, and hands you typed values.

award_rate_pct is the number to watch. It is the winning bid as a percentage of the predetermined price — 89.923 above. In Korea's lowest-price tenders the winner almost always lands in a narrow band just above the statutory floor, so the distribution of this figure across an agency or a work type tells you where to price.

Group	Fields
Winner	winner_ko, winner_business_no, winner_region_ko
Result	award_amount_krw, award_rate_pct, bidder_count, opened_at, awarded_on
Tender	notice_no, notice_seq, title_ko, category, demand_agency_ko, url

Covers all four categories — goods, construction, services and foreign procurement.

Input

Every field is optional. The default is the last 7 days, all categories, 300 records.

Field	Type	Notes
startDate / endDate	date	YYYY-MM-DD, Korea time
categories	array	goods, construction, service, foreign
keywords	array	Match on tender title, winning company, agency or region
minAwardAmountKrw	integer	Skip awards below this amount
maxItems	integer	Stop after N records. 0 = no limit

Records are interleaved across categories, so a capped run still returns a representative mix rather than 300 construction contracts.

Who this is for

• Bidders calibrating price — pull the award rates for your work type and agency and you can see the band the winners actually land in
• Competitive intelligence — track a rival by business number and watch what they win, from whom, and at what discount
• Market sizing — how much an agency actually spends, by category, over time
• Screening and KYC tools that need Korean public-sector contract history keyed to a business registration number
• AI agents needing Korean procurement outcomes as structured context

Pairs with Korea Public Tenders (나라장터) for the notices and Korea Tender Base Prices (기초금액) for the pricing anchor. Join on notice_no and you have the full arc: what was tendered, what it was anchored to, and what it went for.

Notes

Source. 조달청 낙찰정보서비스, published on Korea's national open-data portal under an unrestricted licence (이용허락범위 제한 없음). Every record carries a source field and a url back to the original notice.

This is an API client, not a scraper. Data comes from the government's own REST API with a registered key. The g2b.go.kr website is never touched, so nothing here breaks when the site is redesigned.

No personal data. The upstream API returns the winner's CEO name, phone number, full street address and staff contact. None of it is emitted. The address is reduced to province and city (경상남도 양산시) — enough to analyse region-restricted tendering, not enough to identify anyone. Company name and business registration number are published corporate identifiers and are kept.
