## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Korea Company Check (KYB): Business Status & ID Crosswalk

Verify South Korean counterparties in bulk. Paste company names or any Korean company ID. For each one you get:

- one canonical entity with all its IDs;
- the company's live tax registration status from the National Tax Service.

### What it does

1. **Resolve.** Names are matched in Korean or English. Legal forms (주식회사, ㈜, Co., Ltd.) are ignored, typos are tolerated and former names match (NHN → NAVER).

   IDs are recognised automatically:

   | Input | Detected as |
   |---|---|
   | 10 digits | Business registration no. (사업자등록번호) |
   | 13 digits | Corporate registration no. (법인등록번호) |
   | 8 digits | OpenDART `corp_code` |
   | 6 characters | Stock code |
   | 20 characters | LEI |

   Check digits are verified before any lookup. The index covers about 120,000 companies: OpenDART filers, all listed companies and GLEIF LEI records.
2. **Check status.** Every business registration number found or typed in is checked live with the National Tax Service. The check returns:

   - status: `active`, `suspended`, `closed` or `not_registered`;
   - VAT taxpayer type;
   - closure date, if any.

   Numbers you type directly are checked even when the company is not in the index, so small private businesses work too.

### Output

```json
{
  "input": "220-81-62517",
  "match_status": "MATCHED",
  "confidence": 1,
  "name_ko": "NAVER",
  "name_en": "NAVER Corporation",
  "former_names": ["NHN", "네이버컴"],
  "ids": { "bizr_no": "2208162517", "jurir_no": "1101111707178", "corp_code": "00266961", "stock_code": "035420", "lei": "988400ULUQYDB2HQYJ61" },
  "listed_market": "KOSPI",
  "established": "1999-06-02",
  "tax_status": { "status": "active", "status_ko": "계속사업자", "vat_type": "부가가치세 일반과세자", "closed_date": null, "source": "National Tax Service", "as_of": "2026-10-14T11:19:09Z" },
  "candidates": [],
  "sources": ["opendart:corpCode", "opendart:company", "gleif"]
}
```

`match_status` values:

- `MATCHED`
- `AMBIGUOUS` or `LOW_CONFIDENCE`: candidates are listed for you to pick from
- `NO_MATCH`
- `INVALID`: bad check digit or format

### Pricing

Pay per event:

- **$0.005 per company matched** (`MATCHED` only; ambiguous, unmatched and invalid rows are free).
- **$0.002 per tax status check** answered by the National Tax Service. Numbers that fail the check digit are rejected without a lookup and not charged.

**Free Apify plan:** at most 10 companies per run.

### Limits and notes

- These are facts from official sources (National Tax Service, OpenDART, GLEIF), each with its source and time. They are not a credit rating or a compliance determination.
- Tax status results are not stored.
- The same services are also sold per call over x402 (USDC on Base): https://x402.pokt-agent.com/

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "companies": [
        "Samsung Electronics",
        "220-81-62517",
        "카카오"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("pokt-agent-kr/korea-company-check").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.

## CLI example

```bash
echo '{
  "companies": [
    "Samsung Electronics",
    "220-81-62517",
    "카카오"
  ]
}' |
apify call pokt-agent-kr/korea-company-check --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,pokt-agent-kr/korea-company-check"
        }
    }
}
```

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).
