Summary

Queries Korean real estate transaction data from the Ministry of Land, Infrastructure and Transport via a proxy endpoint. You can look up actual sale prices and rental deposits for apartments, officetels, villas, single-family homes, and commercial buildings by region and date. It handles the two-step flow: resolve region names to administrative codes, then fetch transactions for a given month. Responses include median/min/max prices and individual deals with building names, floor area, and transaction dates. All prices are in 10,000 won units. The proxy handles API keys upstream, so you just make HTTP calls. Built on tae0y's real-estate-mcp work. This is official reported transaction data, not broker listings, so it's clean but a month or two behind.

Korean Real Estate Search

What this skill does

기본적으로 https://k-skill-proxy.nomadamas.org/v1/real-estate/... 로 요청해서 한국 부동산 실거래가/전월세 데이터를 조회한다. 국토교통부(MOLIT) 실거래가 신고 데이터를 기반으로 한다.

When to use

  • "잠실 리센츠 2024년 매매 실거래가 찾아줘"
  • "마포구 아파트 전세 실거래가 보여줘"
  • "성수동 오피스텔 월세 실거래 데이터 볼래"
  • "강남구 연립다세대 매매 실거래가"
  • "용산구 상업업무용 건물 거래 내역"

When not to use

  • 해외 부동산 시세/거래 조회
  • 실거래가가 아닌 민간 호가/매물 비교만 필요한 경우
  • 세금/등기/중개 법률자문처럼 판단이 필요한 경우
  • 청약홈 분양/당첨 조회 (아직 미지원)

Inputs

  • q: 지역명 (region-code endpoint, 예: "서울 강남구", "마포구")
  • lawd_cd: 5자리 법정동 코드 (transaction endpoint, 예: "11680")
  • deal_ymd: 6자리 거래년월 YYYYMM (예: "202403")
  • num_of_rows: 조회 건수 (기본 100, 최대 1000)

Prerequisites

없음. 사용자는 별도 API key를 준비할 필요가 없다. upstream key는 proxy 서버에서만 주입한다.

Default path

추가 client API 레이어는 불필요하다. 그냥 프록시 서버에 HTTP 요청만 넣으면 된다.

KSKILL_PROXY_BASE_URL 환경변수가 있으면 그 값을 사용하고, 없으면 기본 경로 https://k-skill-proxy.nomadamas.org 를 사용한다.

Supported endpoints

지역코드 조회

GET /v1/real-estate/region-code?q={지역명}

실거래가/전월세 조회

GET /v1/real-estate/:assetType/:dealType?lawd_cd={코드}&deal_ymd={년월}

Example requests

지역코드 조회:

curl -fsS --get 'https://k-skill-proxy.nomadamas.org/v1/real-estate/region-code' \
  --data-urlencode 'q=강남구'

아파트 매매 실거래가 조회:

curl -fsS --get 'https://k-skill-proxy.nomadamas.org/v1/real-estate/apartment/trade' \
  --data-urlencode 'lawd_cd=11680' \
  --data-urlencode 'deal_ymd=202403'

오피스텔 전월세 조회:

curl -fsS --get 'https://k-skill-proxy.nomadamas.org/v1/real-estate/officetel/rent' \
  --data-urlencode 'lawd_cd=11680' \
  --data-urlencode 'deal_ymd=202403'

Response shape

지역코드 응답

{
  "results": [
    { "lawd_cd": "11680", "name": "서울특별시 강남구" }
  ],
  "query": "강남구",
  "proxy": { "name": "k-skill-proxy", "cache": { "hit": false, "ttl_ms": 300000 } }
}

매매 실거래가 응답

{
  "items": [
    {
      "name": "래미안 퍼스티지",
      "district": "반포동",
      "area_m2": 84.99,
      "floor": 12,
      "price_10k": 245000,
      "deal_date": "2024-03-15",
      "build_year": 2009,
      "deal_type": "중개거래"
    }
  ],
  "summary": {
    "median_price_10k": 230000,
    "min_price_10k": 180000,
    "max_price_10k": 310000,
    "sample_count": 42
  },
  "query": { "asset_type": "apartment", "deal_type": "trade", "lawd_cd": "11680", "deal_ymd": "202403" },
  "proxy": { "name": "k-skill-proxy", "cache": { "hit": false, "ttl_ms": 300000 } }
}

전월세 응답

매매와 동일 구조이나 아이템에 deposit_10k, monthly_rent_10k, contract_type 이 포함되고, summary에 median_deposit_10k, monthly_rent_avg_10k 등이 들어간다.

Response policy

  • 실거래가/전월세 요청이면 region-code endpoint로 행정구역 코드를 먼저 확인한 뒤 자산 타입별 endpoint로 조회한다.
  • 아파트 매매는 apartment/trade, 아파트 전월세는 apartment/rent 를 우선 사용한다.
  • 오피스텔/빌라/단독주택/상업업무용은 자산 타입에 맞는 endpoint로 라우팅한다.
  • 사용자가 동/건물명/연월을 덜 줬으면 지역, 단지명, 기준 월을 먼저 보강한다.
  • 실거래가와 호가를 섞어 말하지 않는다. 이 스킬은 국토교통부 기반 실거래/전월세 신고 데이터를 다룬다.

Keep the answer compact

  • 지역명 + 자산 타입 + 거래년월
  • 거래 건수 (summary.sample_count)
  • 가격 요약: 중위값, 최소, 최대
  • 상위 3-5건 대표 거래 (이름, 면적, 층, 가격, 날짜)
  • 전월세면 보증금 + 월세 요약도 포함

Failure modes

  • lawd_cd 또는 deal_ymd 형식이 잘못되면 400 응답
  • 프록시 서버에 DATA_GO_KR_API_KEY 가 없으면 503 응답
  • upstream MOLIT API 오류면 502 + molit_api_XXX 에러 코드
  • 해당 지역/기간에 데이터가 없으면 빈 items 배열 반환

Done when

  • 요청 자산 타입에 맞는 endpoint를 선택했다.
  • 필요한 경우 region-code 로 지역코드를 먼저 확인했다.
  • 실거래가/전월세 결과를 조회하고 요약했다.
  • 원본 데이터 출처(국토교통부 실거래가 신고)를 함께 남겼다.

Notes

  • 원본 참고: https://github.com/tae0y/real-estate-mcp/tree/main
  • 공식 데이터 출처: 공공데이터포털 (https://www.data.go.kr)
  • 가격 단위: price_10k, deposit_10k = 만원 단위 (예: 245000 = 24억 5천만원)
  • 취소된 거래는 서버에서 자동 필터링된다.
