## 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

## Japan Market MCP — Cross-Shop Price Comparison for AI Agents

An **MCP server** that lets AI agents (Claude, Cursor, VS Code Copilot, ChatGPT) compare used-good prices across leading Japanese shops in a single tool call. Instead of scraping site by site, an agent queries one server and gets inter-store price gaps for the same product — perfect for **reseller arbitrage**, **price monitoring**, and **market research** on the Japanese second-hand market.

### How it works

The server wraps 7 market-scraping actors behind one MCP endpoint. Each tool returns price, brand, shop, condition and a link per item, with the shop-pair crossed so you see the price spread at a glance.

### Available tools

| Tool | Market | Shop pair |
|---|---|---|
| `search_camera_market` | Used cameras & lenses | Kitamura + Fujiya Camera |
| `search_watch_market` | Luxury watches | Jackroad + Kitamura used watches |
| `search_luxury_market` | Used luxury brands | Komehyo + Jackroad |
| `search_instrument_market` | Used instruments | Digimart + Ishibashi U-BOX |
| `search_offmall_market` | General used goods | OffMall (Hard Off official, 800+ stores) |
| `search_kakaku_prices` | New price comparison | Kakaku.com (aggregated, thousands of shops) |
| `search_car_market` | Used cars | goo-net (nationwide, by body type) |

Each tool takes a keyword (e.g. `SONY α7`, `ROLEX`, `Hermes`, `Fender`) and returns results from the crossed shops. Leaving the keyword empty scans the full category.

### Pricing

Pay per event — **$0.001 per search** + actor start fee. Runs finish in seconds, so a full keyword lookup typically costs well under $0.01.

### Connect as an MCP server

Run it from the Apify Store (Run button), then point your MCP client at the endpoint. It stays in standby mode.

**MCP client config (Claude Desktop / Cursor / VS Code):**

```json
{
  "mcpServers": {
    "japan-market-mcp": {
      "url": "https://fruitful_quintessence--japan-market-mcp.apify.actor/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_APIFY_TOKEN"
      }
    }
  }
}
```

- **URL**: `<your-username>--japan-market-mcp.apify.actor/mcp`
- **Auth**: Apify API token in the `Authorization: Bearer` header (Apify Console → Settings → Integrations)

### Example agent prompts

```
"Compare used prices for Sony a7 III between Kitamura and Fujiya"
→ search_camera_market(keyword="SONY α7 III")

"What's the inter-store price gap for a Rolex Submariner?"
→ search_watch_market(keyword="ROLEX Submariner")

"What's the market price for a Hermes Birkin 25?"
→ search_luxury_market(keyword="Hermes Birkin 25")

"What's a used Fender Stratocaster going for?"
→ search_instrument_market(keyword="Fender Stratocaster")
```

### Use cases

- **Reseller arbitrage** — spot the same product priced differently across shops
- **Market research** — track used prices for cameras, watches, luxury goods, instruments, cars
- **Export sourcing** — goo-net JDM inventory and goo-net price checks for exporters
- **Collector price checks** — condition-ranked physical used items from OffMall

### Data sources

- Each actor collects **factual data only** (product name, price, brand, condition, inventory, URL). No photos or descriptions are harvested.
- All target sites allow crawling via their `robots.txt`.

### Local development

```bash
pip install -r requirements.txt
APIFY_TOKEN=apify_api_xxx python -m src.main
## Streamable HTTP endpoint at http://localhost:3000/mcp
```

# 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 = {};

// Run the Actor and wait for it to finish
const run = await client.actor("fruitful_quintessence/japan-market-mcp").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 = {}

# Run the Actor and wait for it to finish
run = client.actor("fruitful_quintessence/japan-market-mcp").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

```bash
echo '{}' |
apify call fruitful_quintessence/japan-market-mcp --silent --output-dataset

```

## MCP server setup

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

```

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).
