DartLab Data

Structured company data + market data from DART, EDGAR, KRX

한국 DART 공시 + 미국 SEC EDGAR 공시 + KRX 시장 데이터 — 한 dataset, 여러 카테고리

What is this?

Pre-built Parquet files from DartLab — a Python library that turns DART (Korea), EDGAR (US), and KRX disclosure & market data into one structured company map.

한국 DART 전자공시 + 미국 SEC EDGAR 공시 + KRX 거래소 일별 시장 데이터를 동일한 SSOT 로 묶은 데이터셋.

This dataset is the data layer behind DartLab. When you run dartlab.Company("005930") or dartlab.gather("krx", "close"), the library auto-downloads the relevant parquet from this repo — no API key, no manual collection.

7 public categories — each lives at its own subdirectory and is consumed by a specific dartlab engine.

krx/prices — KRX Daily OHLCV ★ NEW

Daily OHLCV + market cap + listed shares for all KRX-listed companies (KOSPI + KOSDAQ), raw long parquet from KRX OpenAPI.

Coverage: 1995-01-04 ~ today (17 yearly partitions: raw-1995.parquet ~ raw-2026.parquet). Update: every weekday at KST 17:00 (after market close + settlement). Auto gap-fill if any cron run is missed. Engine: gather("krx", target, ...) — pivot to wide (rows = stockCode, cols = date) on demand. Adjusted prices (split/bonus/rights) auto-applied via price-series detection (CRSP backward chaining).

import dartlab
dartlab.gather("krx", "close", start="2025-01-01", end="2025-06-30")  # close-price wide
dartlab.gather("krx", "rsi14", start="2025-01-01")                    # 30+ technical indicators
dartlab.gather("krx", "marketCap", start="2025-06-30")                # market cap snapshot

No API key needed — engine reads HF directly. (KRX OpenAPI key is only for operator cron building this dataset.)

landing/map — Industry Map JSON

Pre-built industry graph (nodes + edges) for the Korean market — companies × processes × supply-chain edges. Powers the /map interactive industry visualization.

Engine: dartlab.industry() / c.industry().

Usage

import dartlab

# 1. Korean company — auto-downloads dart/docs + dart/finance + dart/report
c = dartlab.Company("005930")
c.show("BS")                     # balance sheet (dart/finance)
c.show("businessOverview")       # business section text (dart/docs)
c.report("dividend")             # dividend history (dart/report)

# 2. US company — same API, edgar/docs auto
us = dartlab.Company("AAPL")
us.show("IS")

# 3. KRX market data — no API key, HF auto
df = dartlab.gather("krx", "close", start="2024-01-01", end="2024-12-31")  # 1-year wide DataFrame

# 4. Cross-sectional scan
ranked = dartlab.scan("governance/dividend")  # all KR companies, sorted

# 5. Natural language
dartlab.ask("삼성전자 재무건전성 분석해줘")

No API key, no setup — pip install dartlab and the library auto-downloads from this dataset, with local caching.
