## 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.

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).

Amazon Product Advertising API v5 (PA-API v5) 専用の Apify Actor.
**SearchItems** / **GetItems** / **GetVariations** を **AWS Signature V4** で署名して呼び出し、
4 リージョン (co.jp / com / co.uk / de) に対応する。

- **httpx + asyncio** — 高速・同期 I/O なしの非同期通信
- **mypy strict** — 0 errors
- **70 件の pytest** — AWS 署名 / パース / Apify 統合を全てカバー
- **Apify Store 公開対応** — 価格戦略・SEO ドキュメント同梱
- **MIT ライセンス**

***

### 特徴

| 機能 | 説明 |
|------|------|
| SearchItems | キーワード / カテゴリ / 価格フィルタ / ソート (Relevance / PriceLowToHigh / PriceHighToLow / NewestArrivals) |
| GetItems | ASIN を最大 10 件直接指定して取得 |
| GetVariations | 親 ASIN からバリエーション展開 |
| Multi-region | co.jp / com / co.uk / de を `region` 入力で切替 |

***

### 必要環境

- Python 3.11+
- Amazon アソシエイト・アカウント (Associate Tag)
- AWS IAM ユーザー (ProductAdvertisingAPI:\* ポリシー付与済み)
- (デプロイ時のみ) Apify Personal API Token

詳細は [`docs/paapi-setup.md`](docs/paapi-setup.md) を参照.

***

### インストール

```bash
git clone <your-fork-or-clone-url> amazon-paapi-jp-actor
cd amazon-paapi-jp-actor
pip install -r requirements.txt -r requirements-dev.txt
```

***

### ローカル実行

`.env` を `.env.example` からコピーして値を埋める:

```bash
cp .env.example .env
set -a; source .env; set +a
```

#### テスト実行

```bash
## 全 70 件のテスト.
python3 -m pytest tests/ -v

## AWS Signature V4 関連.
python3 -m pytest tests/test_paapi_client.py -v

## 型チェック (mypy strict).
mypy src/
```

#### smoke test (実 API を 1 回呼ぶ)

```bash
LOCAL_KEYWORD="Nintendo Switch" LOCAL_MAX_ITEMS=5 python3 -m src
```

ログに「取得件数: N」と表示されれば成功.

***

### Apify へのデプロイ

```bash
export APIFY_TOKEN=apify_api_xxxxxxxxxxxx
python3 scripts/deploy_apify.py
```

スクリプトは次の順に処理:

1. Actor を作成 (既存なら再利用)
2. Version 作成 (ソースコードを TAR でアップロード)
3. ビルドを起動
4. ビルド完了までポーリング

詳細は [`docs/deploy-guide.md`](docs/deploy-guide.md) を参照.

### 開発メモ

- PA-API v5 は **1 req/sec** のレート制限. 連続実行を避け、必要なら `sleep_ms` 入力で待機を入れる.
- AWS Signature V4 は [`docs/paapi-setup.md`](docs/paapi-setup.md) の IAM ポリシーが必要.
- `mypy.ini` で `strict = True` を有効化済み. CI で 0 errors を維持すること.
- テストは全て httpx をモック化しており、実 API の呼び出しは行わない (1 テスト 0.1 秒以下).

# 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/amazon-paapi-jp-actor").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/amazon-paapi-jp-actor").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/amazon-paapi-jp-actor --silent --output-dataset

```

## MCP server setup

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

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).
