## 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

## Korean Romanizer: Hangul to English letters

Convert Korean text and Korean person names to the Latin alphabet in bulk, following the official **Revised Romanization of Korean** (the system used on Korean road signs and by the Korean government).

### What it does

- **Text mode** romanizes words, sentences, addresses and product titles, and applies the standard pronunciation rules that simple letter-by-letter converters miss:

  | Korean | Letter-by-letter (wrong) | This Actor |
  |---|---|---|
  | 종로 | jongro | **jongno** |
  | 신라 | sinra | **silla** |
  | 같이 | gati | **gachi** |
  | 감사합니다 | gamsahapnida | **gamsahamnida** |

- **Name mode** romanizes person names as surname + given name, using the spellings Koreans actually use on passports: 김민준 → **Kim Minjun**, 이서연 → **Lee Seoyeon**. Compound surnames such as 남궁 and 제갈 are recognized.

### Use cases

- Shipping labels and customs forms for Korean addresses and recipients
- Normalizing Korean names in CRM, HR or KYC data
- Building English product titles and URL slugs from Korean catalogs
- Localization and language-learning apps

### Input

```json
{ "texts": ["안녕하세요", "서울특별시 종로구", "김민준"], "mode": "text" }
```

### Output

```json
{ "original": "종로", "romanized": "jongno", "mode": "text", "hangulChars": 2 }
```

### Pricing

Pay per result: you are charged only for items romanized. No proxies, no browsers, no hidden platform costs: it runs in milliseconds.

### Limits

Romanization follows pronunciation rules algorithmically. A few words whose pronunciation is irregular (some tensed consonants, which Revised Romanization does not mark anyway) may differ from dictionary forms.

# Actor input Schema

## `texts` (type: `array`):

Korean strings to romanize: words, sentences, addresses, product titles or person names.

## `mode` (type: `string`):

'text' applies full Revised Romanization with pronunciation rules. 'name' treats each entry as a person name (surname + given name).

## `nameStyle` (type: `string`):

'common' uses conventional passport spellings (Kim, Lee, Park, Choi). 'rr' uses strict Revised Romanization (Gim, I, Bak, Choe).

## `nameSeparator` (type: `string`):

Text placed between surname and given name in name mode, e.g. a space (Kim Minjun) or a comma and space (Kim, Minjun).

## `capitalize` (type: `boolean`):

Capitalize the first letter of each romanized word in text mode (Seoul Teukbyeolsi instead of seoul teukbyeolsi).

## Actor input object example

```json
{
  "texts": [
    "안녕하세요",
    "서울특별시 종로구",
    "김민준"
  ],
  "mode": "text",
  "nameStyle": "common",
  "nameSeparator": " ",
  "capitalize": false
}
```

# 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 = {
    "texts": [
        "안녕하세요",
        "서울특별시 종로구",
        "김민준"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("peteparkershin/korean-romanizer").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.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = { "texts": [
        "안녕하세요",
        "서울특별시 종로구",
        "김민준",
    ] }

# Run the Actor and wait for it to finish
run = client.actor("peteparkershin/korean-romanizer").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

    "서울특별시 종로구",

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,peteparkershin/korean-romanizer"
        }
    }
}
```

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).
