## 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

## Yahoo! Shopping Japan Product Price & SKU Watchlist

Recheck1–20 known Yahoo!Shopping Japan store product URLs for public asking price, source ordering flags, delivery inventory labels and every on-page SKU/size/color option. One product observation with nested variants per URL. Save a watchlist Task for repeated imports by sellerCode/sourceItemId; no search, market statistics, transaction prices or physical-stock guarantee.

**Price**: $0.003 per delivered product observation.

### Input

`itemUrls`:1–20canonical HTTPS URLs exactly https://store.shopping.yahoo.co.jp/{store}/{item}.html, no query/fragment/port/userinfo. Input duplicates free and removed in order. Single,1axis,2axis and3axis products supported up to1000sourceSKU rows each; extra related-color product links are not fetched or merged. Unknown axes/oversized/missing/mismatched SKU identity fail visibly rather than truncate.

### Output

One yahoo_shopping_product_observation row: canonicalUrl, URL-derivedsellerCode, sourceItemId(srid), sellerManagedItemId, short title, priceJpy(applicablePrice), source taxExcludedPriceJpy|null, currencyJPY, janRaw|null, sourceIsOnSale/sourceIsAvailable/sourceIsPreOrder/sourceIsUsed, deliveryInventoryLabel|null, stockText, axisCount,variantCount,variants,fetchedAtUTC. Variant rows contain originalskuId,1–3axisName/choiceName pairs, sourceIsAvailable, sourceStockText/sourceStockSymbolType and variantPriceJpy|null. For3axes, variantPriceJpy is source individualItem.price.applicablePrice; for1/2axes it is choice.price. Null variantprice stays unknown; never inherit rootprice silently. Source ordering true can coexist with お取り寄せ or 入荷待ち and is not immediate shipment. No physical quantities, future stock alerts or actualpaid-price claim. JAN is raw/unverified, not a unique size identifier. No missing-price0 guess.

### Pricing

USD0.003 product-observed per complete delivered unique product including all nested variants, no startup/search/SKU fee. Source-confirmed unavailable product with valid price is a useful paid observation. HTTP404/access/429/challenge/unknownstructure fail without a negative observation; allsourcework stages before any atomic charged delivery. Platform spending allowance limits input prefix before acquisition, ChargeResult must equal delivered count. SUMMARY/RUN-SUMMARY report paid deliveredRows.

### Limits

21HTTPrequests including robots,180seconds,256MB,4MiBwire/8MiBdecoded perresponse and64MiBtotal,24MiBstagedoutput cap; samehost serialstarts>=2seconds or applicableactualUArobotsdelay. Fixed product host/path, redirect rejection, no cookies/privateaddresses/browser/proxy/login/paidAPI.20products/1000SKUs are hard safety caps, no all-store or all-market coverage claim.

### Privacy and source conditions

Only typed source facts and short product/option labels. No descriptions/photos/media/reviews/customerpersonalization/individualsellerprofiles/contact data/HTML snapshots. On-demand only, source attribution retained. Applicable LYterms prohibit data reuse beyond intended purpose and some unapproved commercial behavior; these are recorded contractual risks under existingDR-0007, not permission. Current linked terms and free public/seller API differences are recorded in the scout.

### Complete SKU CSV export

Raw JSON retains nested variants plus a complete equivalent variantsJson string. Parse variantsJson as JSON to recover every SKU and field. Use ?format=csv\&view=overview: all variants remain in one text cell, avoiding the platform2000column flattening cap for large matrices. No field truncation or extra SKU fee.

### Measured source boundary

A current ordinary search sample included a product with source axisNum=3. The initial0–2axis parser rejected it as unsupported-axes before charged delivery. Current3axis support binds individualItemList SKU IDs, option names/choices, source variant applicablePrice and stock flags to individualItemOptionList definitions and the complete skuIdList key/choice map. The original20URL collection is rerun without excluding this product. More than3axes, unknown/missing/duplicate mappings or over1000SKUs still fail. This observation is not a market-wide coverage estimate. Empty source janCode is retained as an empty raw identifier; it is not a verified JAN.

# 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("jpmarketdata/yahoo-shopping-japan-product-watchlist").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);
});

## MCP server setup

```json

    }
}
```

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).
