## 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

## Mercari Japan Scraper

Scrape product listings, prices, and sold items from [Mercari Japan](https://jp.mercari.com/) -- Japan's largest consumer-to-consumer marketplace.

### Key Features

- **Search by keywords** -- Find products matching any query on Mercari Japan
- **Sold item tracking** -- View actual selling prices for resale research (物販リサーチ)
- **Price range filtering** -- Narrow results by minimum/maximum price in JPY
- **Item condition filtering** -- Filter by new, like-new, good, fair, or poor condition
- **Flexible sorting** -- Sort by relevance, price, or newest listings
- **Direct URL scraping** -- Scrape individual product pages for full details
- **Automatic pagination** -- Collect up to 1,000 items per run

### Why Track Sold Items?

For resellers and market researchers, knowing the **actual selling price** is more valuable than the listing price. Set `status` to `sold_out` to see completed transactions and understand real market value.

\*At least one of `searchKeywords` or `productUrls` is required.

### Example Usage

#### Search for Nintendo Switch listings

```json
{
  "searchKeywords": ["Nintendo Switch"],
  "status": "on_sale",
  "sortBy": "price_asc",
  "priceMax": 30000,
  "maxResults": 100
}
```

#### Research sold prices for iPhone 15

```json
{
  "searchKeywords": ["iPhone 15"],
  "status": "sold_out",
  "sortBy": "created_desc",
  "maxResults": 200
}
```

#### Scrape specific product pages

```json
{
  "productUrls": [
    "https://jp.mercari.com/item/m12345678",
    "https://jp.mercari.com/item/m87654321"
  ]
}
```

### Proxy Requirements

This actor uses datacenter proxies (BUYPROXIES94952) with Japan IP addresses by default. If datacenter proxies are unavailable, it falls back to residential proxies. Mercari Japan may block non-Japanese IP addresses.

### Pricing

**$4 per 1,000 items** scraped.

### Limitations

- Mercari may limit search results to approximately 600 items per query
- Heavy scraping may trigger rate limiting or CAPTCHA challenges
- Some fields (description, shippingMethod) are only available on individual product pages
- Results depend on Mercari's page structure; changes to the site may temporarily affect data extraction

## MCP server setup

{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,cloud9_ai/mercari-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).
