## 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.

- **Multi-month queries**: Query multiple year-months in a single run
- **Automatic pagination**: Fetches all pages per region/month combination

### Pricing (Pay-Per-Event)

| Event | Price | When charged |
|-------|-------|-------------|
| Actor start | $0.001 | Once per run |
| Per transaction record | $0.001 | Per record pushed to dataset |

Fetching 1,000 apartment buy records ≈ **$1.001 total**.

***

### Notes

- Region codes are the first 5 digits of the 10-digit 법정동 코드. Use `11` for all of Seoul (slower, large result set).
- The public API rate-limits aggressively. The Actor automatically retries on transient failures.
- Some endpoints return XML regardless of `_type=json` parameter — the Actor handles both formats transparently.
- Data is updated by the Ministry of Land approximately monthly; very recent transactions may not yet appear.

## CLI example

```bash
echo '{}' |
apify call gochujang/korea-real-estate-transactions --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,gochujang/korea-real-estate-transactions"

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).
