Summary

국세청 사업자등록정보 진위확인 및 사업자등록 상태조회를 공공데이터포털 API(k-skill-proxy 경유)로 수행한다.

SKILL.md

국세청 사업자등록정보 진위확인 및 상태조회

What this skill does

공공데이터포털의 국세청_사업자등록정보 진위확인 및 상태조회 서비스를 k-skill-proxy 경유로 호출해 다음을 확인한다.

  • status: 사업자등록번호 기준 상태조회 (계속사업자, 휴업자, 폐업자, 과세유형 등 upstream 응답 그대로 포함)
  • validate: 사업자등록번호 + 개업일자 + 대표자명(및 선택 필드) 기준 진위확인

When to use

  • "이 사업자등록번호가 계속사업자인지 확인해줘"
  • "사업자등록번호 상태조회해줘"
  • "사업자등록번호, 개업일, 대표자명으로 진위확인해줘"
  • 거래처 등록 전 공식 NTS/공공데이터포털 기준 확인이 필요할 때

Prerequisites

  • 인터넷 연결
  • python3
  • 설치된 skill payload 안에 scripts/nts_business_registration.py helper 포함
  • hosted/self-host k-skill-proxy의 /v1/nts-business/status, /v1/nts-business/validate route 접근 가능

Credential requirements

  • 사용자 측 필수 시크릿 없음.
  • KSKILL_PROXY_BASE_URL — self-host·별도 프록시를 쓸 때만 설정. 비우면 기본 hosted https://k-skill-proxy.nomadamas.org 를 사용한다.
  • DATA_GO_KR_API_KEY 는 프록시 운영 서버 환경에만 둔다. 공공데이터포털에서 국세청_사업자등록정보 진위확인 및 상태조회 서비스 활용신청이 되어 있어야 한다.

Validate privacy boundary

  • validate는 대표자명(p_nm), 개업일자(start_dt), 주소·상호 같은 선택 메타데이터를 hosted proxy와 공공데이터포털 upstream으로 전송한다.
  • hosted proxy는 validate 성공 응답을 캐시하지 않고, 프록시 query echo를 붙이지 않으며, upstream이 요청값을 되돌려도 민감 입력 필드를 응답에서 제거한다.
  • 프록시의 기본 Fastify request logging은 꺼져 있다. 운영자가 별도 로그를 켠 self-host 환경에서는 요청 본문 로깅 정책을 직접 점검해야 한다.
  • hosted proxy 경유가 부담스러운 진위확인 업무는 KSKILL_PROXY_BASE_URL로 직접 운영하는 self-host proxy를 지정한다.

Official surfaces

  • 공공데이터포털 문서: https://www.data.go.kr/tcs/dss/selectApiDataDetailView.do?publicDataPk=15081808
  • 상태조회 upstream: POST https://api.odcloud.kr/api/nts-businessman/v1/status?serviceKey=...
  • 진위확인 upstream: POST https://api.odcloud.kr/api/nts-businessman/v1/validate?serviceKey=...
  • 프록시 route: POST /v1/nts-business/status, POST /v1/nts-business/validate

Inputs

상태조회

  • b_no: 사업자등록번호 10자리. 하이픈은 허용되며 helper/proxy가 숫자만 남긴다.
  • 한 요청은 최대 100개까지 보낸다.

진위확인

필수:

  • b_no: 사업자등록번호 10자리
  • start_dt: 개업일자 YYYYMMDD (하이픈/점 허용)
  • p_nm: 대표자 성명

선택:

  • p_nm2: 대표자 성명2
  • b_nm: 상호
  • corp_no: 법인등록번호
  • b_sector: 주업태명
  • b_type: 주종목명
  • b_adr: 사업장주소

텍스트 필드는 NTS 입력 규격에 맞춰 보수적으로 길이를 제한한다(p_nm/p_nm2 30자, b_nm 200자, b_sector/b_type 100자, b_adr 500자). corp_no는 제공할 경우 숫자 13자리여야 한다.

Workflow

  1. 사용자 입력에서 사업자등록번호는 숫자 10자리인지 확인한다.
  2. 상태조회만 필요하면 status를 호출한다.
  3. 진위확인은 최소 b_no, start_dt, p_nm이 있을 때만 호출한다.
  4. 개인정보/거래처 정보는 필요한 필드만 보내고, 프록시 응답을 그대로 보존하되 핵심 상태/진위 결과를 짧게 요약한다.
  5. upstream이 upstream_not_configured, 활용신청 미승인, 인증키 오류 등을 반환하면 설정/승인 문제로 안내한다.

CLI examples

python3 scripts/nts_business_registration.py status \
  --b-no 123-45-67890
python3 scripts/nts_business_registration.py validate \
  --business-json '{"b_no":"123-45-67890","start_dt":"2020-01-31","p_nm":"홍길동","b_nm":"테스트상사"}'

Direct proxy examples

curl -fsS -X POST "$KSKILL_PROXY_BASE_URL/v1/nts-business/status" \
  -H 'content-type: application/json' \
  -d '{"b_no":["123-45-67890"]}'
curl -fsS -X POST "$KSKILL_PROXY_BASE_URL/v1/nts-business/validate" \
  -H 'content-type: application/json' \
  -d '{"businesses":[{"b_no":"123-45-67890","start_dt":"20200131","p_nm":"홍길동"}]}'

Failure modes

  • 400 bad_request: 사업자등록번호가 10자리가 아니거나 진위확인 필수 필드가 빠짐.
  • 503 upstream_not_configured: 프록시 서버에 DATA_GO_KR_API_KEY가 없음.
  • upstream 인증/활용신청 오류: API 키가 해당 서비스에 승인되지 않았거나 만료/오류 상태.
  • 빈 결과 또는 진위불일치: 공식 응답의 valid, valid_msg, b_stt 값을 그대로 근거로 설명한다.

Done when

  • 상태조회는 공식 응답의 b_stt, b_stt_cd, tax_type 등 핵심 필드를 확인했다.
  • 진위확인은 valid, valid_msg 결과를 확인했다.
  • API 키는 사용자에게 요구하지 않고 프록시 서버에만 둔다는 점을 지켰다.
