## 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

## Kakaku.com Price Comparison Scraper

Scrape Kakaku.com, Japan's #1 price comparison site: product name, lowest price, shop count, rating, reviews, and images. No API key needed. Perfect for price monitoring, market research, and competitor analysis.

### Use cases

- 価格.comの最安値と店舗数を継続的に追跡する
- 自社商品の価格競争力を競合と比較する
- 値下がりタイミングを検知して仕入れ判断に使う
- カテゴリ単位で市場価格の分布を分析する
- レビュー数と評価から売れ筋を把握する

### Input

| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
| `keyword` | string | Yes | `"iPhone"` | Product search keyword (e.g., 'iPhone 16', 'ノートパソコン', '電子レンジ') |
| `maxResults` | integer | No | `30` | Maximum number of products to scrape (1-200) |
| `proxyConfiguration` | object (proxy) | No | `{"useApifyProxy":true}` | Proxy settings |

#### Example input

```json
{
  "keyword": "iPhone",
  "maxResults": 5,
  "proxyConfiguration": {
    "useApifyProxy": true
  }
}
```

### Output

Each dataset item looks like this — real output from an actual run of this Actor:

```json
{
  "productName": "iPhone 17e",
  "maker": "Apple",
  "lowestPrice": 104748,
  "shopCount": null,
  "rating": 4.26,
  "reviewCount": 51,
  "imageUrl": "https://img1.kakaku.k-img.com/images/productimage/ll/J0000050033.jpg",
  "productUrl": "https://kakaku.com/keitai/smartphone/model/M0000001194/",
  "itemId": null,
  "category": "スマートフォン",
  "scrapedAt": "2026-09-06T15:21:24.466Z"
}
```

| Field | Type |
|---|---|
| `productName` | string |
| `maker` | string |
| `lowestPrice` | number |
| `shopCount` | null |
| `rating` | number |
| `reviewCount` | number |
| `imageUrl` | string |
| `productUrl` | string |
| `itemId` | null |
| `category` | string |
| `scrapedAt` | string |

The dataset also ships a preset table view (**Overview**), so the key columns are readable straight away in Apify Console, and exportable to JSON, CSV, Excel, or XML.

### How to run it

**In Apify Console** — open the Actor, fill in the input form, click **Start**, then download the results from the **Dataset** tab.

**With the JavaScript client**

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

const client = new ApifyClient({ token: 'YOUR_APIFY_TOKEN' });

const run = await client.actor('cloud9_ai/kakaku-scraper').call({
  "keyword": "iPhone",
  "maxResults": 5,
  "proxyConfiguration": {
    "useApifyProxy": true
  }
});

const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items);
```

**With the Python client**

```python
from apify_client import ApifyClient

client = ApifyClient('YOUR_APIFY_TOKEN')

run = client.actor('cloud9_ai/kakaku-scraper').call(run_input={
  "keyword": "iPhone",
  "maxResults": 5,
  "proxyConfiguration": {
    "useApifyProxy": True
  }
})

for item in client.dataset(run['defaultDatasetId']).iterate_items():
    print(item)
```

**With the API** — `POST https://api.apify.com/v2/acts/cloud9_ai~kakaku-scraper/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN` with the input JSON as the body.

### Notes and limits

- No API key, account, or login is needed — just the input above.
- `maxResults` caps how much a single run collects, which is also what caps the run's cost.
- Failed requests are retried automatically.
- Supports Apify Proxy via `proxyConfiguration`; the default is fine for most runs.
- Only publicly available data is collected. How you use the output is your responsibility, including the source's terms of use and any applicable data-protection law.

### Support

## CLI example

```bash
echo '{
  "keyword": "iPhone",
  "maxResults": 5
}' |
apify call cloud9_ai/kakaku-scraper --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,cloud9_ai/kakaku-scraper"
        }
    }
}

```

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).
