제작자가 쓴 설명(영어 원문)
Korean public holidays, business-day math, and MOLIT real-estate transactions as MCP tools.
이 세 가지는 절대 하나의 점수로 합치지 않아요. 의견, 측정, 인기는 서로 다른 것이니까요.
이 서버는 아직 쉬운 말로 된 요약을 쓰지 못했어요. 아래는 레지스트리에서 읽어 온 사실이에요.

Clean, developer-friendly REST APIs for Korean public data. Korean government open data is powerful but hard to consume — Korean-only docs, XML responses, legacy auth. This suite normalizes it into simple JSON APIs.
▶ [Try it on RapidAPI](https://rapidapi.com/dch0202/api/korea-real-estate-holidays) — free tier, no setup. Hosted and auto-updated; same code as this repo. For AI agents, it's on the MCP Registry — uvx korea-data-mcp.
| API | Status | Description |
|---|---|---|
| Holidays & Business Days | ✅ v1 | Korean public holidays (incl. substitute & temporary holidays) and business-day calculations |
| Real Estate Transactions | ✅ v1 | Normalized MOLIT real transaction prices (apartment/officetel/land, sale & rent) — nationwide (261 sigungu) |
| Address Toolkit | 🚧 planned | Road/lot address conversion, romanization |
| Business Registration | 🚧 planned | BRN validation & enrichment |
Hosted (recommended) — a maintained instance with a free tier and no setup:
→ [Subscribe on RapidAPI](https://rapidapi.com/dch0202/api/korea-real-estate-holidays), grab your key, and call any endpoint. RapidAPI injects the key for you — copy a ready-made snippet from its Code Snippets panel.
| RapidAPI (hosted) | Self-host | |
|---|---|---|
| Setup | API key in seconds | data.go.kr key + server + cron |
| Data refresh | automatic (we run the sync) | you manage the scheduler |
| Cost | free tier, then paid | free (your own infra) |
Both run the exact same code (this repo). Pick RapidAPI if you'd rather not operate data pipelines; self-host if you want full control.

Covers official public holidays, substitute holidays (대체공휴일), temporary holidays (임시공휴일), and election days — the cases most global holiday APIs get wrong for Korea.
Normalized MOLIT (Ministry of Land) real transaction prices — apartment, officetel, and land; sale, jeonse, and monthly-rent — as clean English JSON with cursor pagination.

Daily sync ingests the current + previous month; use the backfill CLI for history:
uv run python scripts/backfill.py --from 2025-01 --to 2025-12 --regions 11680,11650
Environment variables (prefix KDS_, .env supported):
| Variable | Default | Description |
|---|---|---|
KDS_DEV_MODE | false | Skip API-key auth (local dev) |
KDS_API_KEYS | — | Comma-separated accepted API keys |
KDS_PROXY_SECRETS | — | Comma-separated marketplace proxy secrets |
KDS_DB_PATH | data/kds.db | SQLite path |
KDS_DATA_GO_KR_KEY | — | data.go.kr service key (optional; enables holiday + real-estate sync) |
KDS_ENABLE_SCHEDULER | true | Holiday (weekly) + real-estate (daily) sync scheduler |
KDS_RE_REGIONS | all 261 nationwide sigungu | Comma LAWD codes to sync (subset override) |
KDS_RE_DATASETS | all | Comma dataset keys (apt_trade, apt_rent, offi_trade, offi_rent, land_trade) |
# Install & start (auto-restart on crash, start at login)
./scripts/install-daemon.sh

To keep the machine awake for serving, disable system sleep (sudo pmset -a sleep 0) or use a dedicated always-on machine. See deploy/cloudflared.example.yml for exposing the API via Cloudflare Tunnel without opening ports.
The read path and the write path are separated so traffic scales independently:
busy_timeout — readers never block the daily writer and vice-versa, and multiple read workers can run concurrently.scripts/run.sh runs uvicorn with --workers ${KDS_WORKERS:-2} and KDS_ENABLE_SCHEDULER=false. Each worker is a separate process (separate GIL); WAL lets them all read at once. Raise KDS_WORKERS to scale reads with cores.com.choiyounggi.kds-sync, 04:00) via scripts/sync.py — never inside the API server, so a multi-thousand-row batch never competes with request handling for the GIL.Cache-Control: no-store for security. The real-estate data is public and changes at most daily — if origin load grows, serve it with a short Cache-Control: public, max-age=... and let the CDN absorb reads.The app is hardened at the code layer (API-key auth fail-closed, parameterized SQL, strict input validation, security headers on every response including 5xx, docs/schema off by default, sanitized errors). The following are edge/deploy responsibilities that must be in place before opening the tunnel:
127.0.0.1 only).KDS_ENABLE_DOCS unset (or false) in production; set true only to serve /docs /openapi.json at the origin.A static, SEO-optimized marketing site is generated from the live DB by scripts/gen_site.py. For every region that has real transaction data it emits a Korean landing page (the query users actually type — "강남구 아파트 실거래가 API" — backed by real MOLIT stats, a working curl example, and a signup CTA), plus a holidays pillar page, a home page, sitemap.xml, and robots.txt.
Quality gate (important): a region is only published if it has at least MIN_SALE_ROWS (30) apartment-sale rows. Regions without enough data are skipped — this deliberately avoids thin/doorway pages, which search engines penalize.
# generate into site/dist (reads data/kds.db)
uv run python scripts/gen_site.py --out site/dist
Config is env-driven so the same generator works for any domain (put these in deploy/site.env, gitignored — copy deploy/site.env.example):
| Env | Meaning |
|---|---|
KDS_SITE_URL | canonical/sitemap base, e.g. https://korea-data.cloud |
KDS_API_ORIGIN | origin shown in the on-page curl examples, e.g. https://api.korea-data.cloud |
KDS_CTA_URL | signup call-to-action (RapidAPI / Zyla / Postman listing) |
KDS_SITE_DIR | output dir the app serves (default site/dist) |
The FastAPI app serves site/dist at all non-API paths (app.mount("/")), while /v1/* stays the JSON API. The two get different response headers: the API keeps its locked-down default-src 'none' CSP + no-store; the site gets an HTML-renderable CSP (script-src 'none', inline styles allowed) + public cache. Files are read from disk per request, so regenerating the site goes live with no app restart — only a code change needs a restart.
The site is served on the same host as the API (api.korea-data.cloud) — the API lives under /v1, the site everywhere else — so no new tunnel hostname or DNS is needed. One-time on the serving host:
cp deploy/site.env.example deploy/site.env # KDS_SITE_URL == KDS_API_ORIGIN == https://api.korea-data.cloud
uv run python scripts/gen_site.py --out site/dist # generate once
Submit https://api.korea-data.cloud/sitemap.xml once in Google Search Console.
Want the site on a bare
korea-data.cloud/wwwlater? Add an ingress rule
pointing that hostname at the same
http://127.0.0.1:8642, route its DNS, and
switch
KDS_SITE_URLto it. Not required — the api host works for SEO today.
First run needs history: the daily sync only ingests the current month. To give
pages real depth, backfill once —
uv run python scripts/backfill.py --from 2025-07 --to 2026-06 --regions --datasets apt_trade,apt_rent.
deploy/com.choiyounggi.kds-site.plist regenerates the site daily at 04:30 (right after the 04:00 sync) via scripts/publish_site.sh. Because the app serves from disk, the refreshed pages are live immediately — no restart, no external deploy:
cp deploy/com.choiyounggi.kds-site.plist ~/Library/LaunchAgents/
launchctl bootstrap "gui/$(id -u)" ~/Library/LaunchAgents/com.choiyounggi.kds-site.plist tail -f ~/Library/Logs/kds/site.out.log
Uptime note: since the site is served by the local app (not a CDN), its SEO
availability tracks the machine — keep it awake for serving (
pmset, as the API
already requires). If always-on hosting is wanted later, the same
site/distcan
be pushed to Cloudflare Pages instead.
The API is also packaged as a standalone Model Context Protocol server — packages/korea-data-mcp/ — so AI agents (Claude Desktop/Code, Cursor, …) can discover and call the endpoints directly. It is its own minimal package (deps: mcp, httpx) and is what gets published to PyPI / listed in the MCP Registry.
Quick add (before PyPI, straight from this repo — users bring their own key):
claude mcp add korea-data-suite --env KDS_API_KEY=<key> \
-- uvx --from "git+https://github.com/choiyounggi/korea-data-suite#subdirectory=packages/korea-data-mcp" korea-data-mcp
See packages/korea-data-mcp/README.md for tools, client config, and uvx korea-data-mcp (once on PyPI).
