Korean financial data SDK — DART 5소스 교차검증, LLM-ready

Project description

hyean — Korean financial data SDK

DART 원문 기반 5소스 교차검증 한국 상장기업 재무 데이터. 모든 수치에 confidence 등급과 원문 출처(report_url + anchor)가 따라옵니다.

pip install git+https://github.com/twiw49/hyean-sdk.git   # 또는: pip install hyean
import hyean as hy

hy.set_api_key("hyn_live_xxxx")        # 또는 export HYEAN_API_KEY=...
# base_url 기본값 = https://api.hyean.io (생략 가능)

# 재무제표 → pandas DataFrame (식별자: 종목코드 / corp_code / 기업명)
bs = hy.load_balance("삼성전자")
is_ = hy.load_income("005930", min_confidence="high")   # 품질 필터
cf  = hy.load_cashflow("00126380")

dart-fss와 다른 점 — point-in-time(정정 소급반영)

# 특정 시점 기준으로 본 재무 — 이후 정정공시를 반영/미반영해 백테스트 무결성 확보
bs_then = hy.load_balance("005930", as_of="2023-03-31")

as_of는 survivorship bias와 미반영 정정으로 백테스트가 틀어지는 문제를 막습니다 — 무료 오픈소스가 싸게 제공하지 못하는 지점입니다.

원문 추적

bs = hy.load_balance("005930")
url = hy.source_url(bs, "BS_AST_TOT", "2024")   # 이 숫자의 DART 원문 위치

CompanyHub — 한 기업, 여러 관점

hub = hy.CompanyHub("005930")
hub.balance, hub.income, hub.cashflow, hub.audit, hub.profile, hub.risk
