## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Korea Tender Winners (낙찰자 현황) — Company, Amount, Award Rate

Korea's public sector awards roughly **1,200 contracts a day**. This Actor returns
each one as a clean record: which company won, its business registration number, the
amount in KRW, the award rate, how many firms bid, and where the winner is based.

The government publishes all of it — in Korean, across four separate endpoints, with
the numbers arriving as strings. This Actor merges the four, translates the schema,
and hands you typed values.

### What you get

```json
{
  "notice_no": "R26BK01701770",
  "title_ko": "양산천(효충교~삽량교) 우안 풀베기사업(추계)",
  "category": "Construction",
  "winner_ko": "모아물산 주식회사",
  "winner_business_no": "1878601218",
  "winner_region_ko": "경상남도 양산시",
  "award_amount_krw": 39141330,
  "award_rate_pct": 89.923,
  "bidder_count": 48,
  "opened_at": "2026-09-02T11:00:00",
  "awarded_on": "2026-09-02",
  "demand_agency_ko": "경상남도 양산시",
  "url": "https://www.g2b.go.kr/link/PNPE027_01/single/?bidPbancNo=R26BK01701770&bidPbancOrd=000",
  "source": "조달청 나라장터 (Public Procurement Service, Korea) via data.go.kr"
}
```

**`award_rate_pct` is the number to watch.** It is the winning bid as a percentage of
the predetermined price — 89.923 above. In Korea's lowest-price tenders the winner
almost always lands in a narrow band just above the statutory floor, so the
distribution of this figure across an agency or a work type tells you where to price.

| Group | Fields |
|---|---|
| **Winner** | `winner_ko`, `winner_business_no`, `winner_region_ko` |
| **Result** | `award_amount_krw`, `award_rate_pct`, `bidder_count`, `opened_at`, `awarded_on` |
| **Tender** | `notice_no`, `notice_seq`, `title_ko`, `category`, `demand_agency_ko`, `url` |

Covers all four categories — goods, construction, services and foreign procurement.

### Input

Every field is optional. The default is the last 7 days, all categories, 300 records.

| Field | Type | Notes |
|---|---|---|
| `startDate` / `endDate` | date | `YYYY-MM-DD`, Korea time |
| `categories` | array | `goods`, `construction`, `service`, `foreign` |
| `keywords` | array | Match on tender title, winning company, agency or region |
| `minAwardAmountKrw` | integer | Skip awards below this amount |
| `maxItems` | integer | Stop after N records. `0` = no limit |

Records are interleaved across categories, so a capped run still returns a
representative mix rather than 300 construction contracts.

### Who this is for

- **Bidders** calibrating price — pull the award rates for your work type and agency
  and you can see the band the winners actually land in
- **Competitive intelligence** — track a rival by business number and watch what they
  win, from whom, and at what discount
- **Market sizing** — how much an agency actually spends, by category, over time
- **Screening and KYC tools** that need Korean public-sector contract history keyed to
  a business registration number
- **AI agents** needing Korean procurement outcomes as structured context

Pairs with **Korea Public Tenders (나라장터)** for the notices and **Korea Tender Base
Prices (기초금액)** for the pricing anchor. Join on `notice_no` and you have the full
arc: what was tendered, what it was anchored to, and what it went for.

### Notes

**Source.** [조달청 낙찰정보서비스](https://www.data.go.kr/data/15129394/openapi.do),
published on Korea's national open-data portal under an unrestricted licence
(이용허락범위 제한 없음). Every record carries a `source` field and a `url` back to
the original notice.

**This is an API client, not a scraper.** Data comes from the government's own REST
API with a registered key. The g2b.go.kr website is never touched, so nothing here
breaks when the site is redesigned.

**No personal data.** The upstream API returns the winner's CEO name, phone number,
full street address and staff contact. **None of it is emitted.** The address is
reduced to province and city (`경상남도 양산시`) — enough to analyse region-restricted
tendering, not enough to identify anyone. Company name and business registration
number are published corporate identifiers and are kept.

### Development

```bash
export G2B_SERVICE_KEY='...'   # data.go.kr 인증키 (다른 g2b Actor와 같은 키)
python3 probe.py               # 오퍼레이션·필드명 대조
apify push                     # 배포
```

업스트림 필드가 바뀌면 조용히 빈 값이 나간다. 이상하면 `probe.py`부터 돌릴 것.

## CLI example

```bash
echo '{}' |
apify call atomo-studio/korea-g2b-tender-winners --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,atomo-studio/korea-g2b-tender-winners"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
