## 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-jma-weather

This Apify actor scrapes **JMA** data from Japanese weather and meteorological data sources. It produces structured JSON or CSV suitable for resale arbitrage, market research, price monitoring, AI training pipelines, and competitor analysis.

### What it scrapes

For each item found, the actor extracts:

- **Title** (item name in Japanese and English where available)
- **Price** (JPY, with discount/original price distinction)
- **Condition** (new, used, refurbished, etc.)
- **Seller** (name, rating, shop ID)
- **Category** (taxonomy path)
- **Images** (URLs, alt text)
- **URL** (canonical item link)
- **Timestamp** (when scraped)

### Input

The actor accepts the following input fields:

- `startUrls` (array): Initial listing or category URLs to seed the crawl
- `maxItems` (integer, default 1000): Maximum number of items to scrape per run
- `proxyConfiguration` (object): Proxy settings (residential or datacenter based on target)
- `searchKeyword` (string, optional): Filter listings by keyword
- `priceRange` (object, optional): { min, max } in JPY to filter listings

### Output

Results are written to the default Apify dataset in this shape:

```json
{
  "title": "...",
  "priceJpy": 12345,
  "condition": "used",
  "seller": { "name": "...", "rating": 4.5 },
  "category": ["...", "..."],
  "images": ["https://..."],
  "url": "https://...",
  "scrapedAt": "2026-09-05T00:00:00Z"
}
```

### Pricing

Pay-per-event: **charged per item scraped**. See the actor's pricing tab for the current per-item rate. No monthly subscription required; you pay only for what you actually collect.

### Use cases

- **Resale arbitrage**: identify underpriced listings on one marketplace to flip on another
- **Market research**: track price trends, new arrivals, and seller behaviour over time
- **Price monitoring**: alert when items cross your buy/sell thresholds
- **AI training data**: build labelled datasets for classification, price prediction, and listing generation
- **Competitor analysis**: monitor which sellers dominate which categories

### Notes

This actor is part of a suite covering major Japanese marketplaces and second-hand chains. Source listings are public; the actor respects robots.txt and includes polite crawl delays. For high-volume or commercial scraping, configure residential proxies via the input schema.

# 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-jma-weather").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);
});

# 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-jma-weather").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-jma-weather --silent --output-dataset

```

## MCP server setup

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

```

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).
