No pre-built Yahoo! Auctions Japan scraper API? No problem. Bright Data's AI Scraper Builder generates a custom Yahoo! Auctions Japan scraper in just a few clicks — no coding required.

Open the Yahoo! Auctions Japan AI Scraper Builder →

Choose the domain, outline your data requirements, and let our AI scraper builder automatically create the API.

1. Describe data needs in plain English
2. AI instantly generates the scraper API
3. Run API requests for immediate results
4. Edit the code in the built-in IDE, if needed

Once built, your scraper gets a Web Scraper ID (gd_xxxxxxxxxxxx) — copy it for the Setup step below.

• Python 3.9 or higher
• A Bright Data account (free trial available)
• A Bright Data API token (how to get one)
• A Web Scraper ID for Yahoo! Auctions Japan (from the build step above)

1. Clone this repository

   git clone https://github.com/luminati-io/yahoo-auctions-price-tracker.git
   cd yahoo-auctions-price-tracker

2. Install dependencies

   pip install -r requirements.txt

3. Configure credentials

   Copy .env.example to .env and fill in your values:

   cp .env.example .env

   BRIGHTDATA_API_TOKEN=your_api_token_here
   BRIGHTDATA_DATASET_ID=your_dataset_id_here

   Your Web Scraper ID Paste the Web Scraper ID from your AI Scraper Builder dashboard into BRIGHTDATA_DATASET_ID (format: gd_xxxxxxxxxxxx).

Once your Yahoo! Auctions Japan scraper is built and your Web Scraper ID is configured in .env, the Python interface works the same way:

Pass a list of Yahoo! Auctions Japan product URLs to retrieve structured price data:

from price_tracker import track_prices

urls = [
    "https://www.auctions.yahoo.co.jp/product/sample-item-123456",
    # Add more product URLs here
]

results = track_prices(urls)
for item in results:
    print(f"{item.get('title')} - {item.get('final_price', item.get('price'))} {item.get('currency', '')}")

Or run directly:

python price_tracker.py

Find products matching a keyword search:

from price_tracker import discover_by_keyword

results = discover_by_keyword("laptop", limit=50)

Collect all products from a Yahoo! Auctions Japan category page:

from price_tracker import discover_by_category

results = discover_by_category(
    "https://auctions.yahoo.co.jp/category/example",
    limit=100,
)

Each result record contains the following fields:

[
  {
    "url": "https://www.auctions.yahoo.co.jp/product/sample-item-123456",
    "title": "Example Product Name",
    "brand": "Example Brand",
    "initial_price": 59.99,
    "final_price": 44.99,
    "currency": "USD",
    "discount": "25%",
    "in_stock": true,
    "rating": 4.5,
    "reviews_count": 1234,
    "images": ["https://auctions.yahoo.co.jp/images/product1.jpg"],
    "description": "Product description text...",
    "timestamp": "2025-01-15T10:30:00Z"
  }
]

The trigger_collection() function accepts optional parameters to control data collection:

Example with options:

from price_tracker import trigger_collection, get_results

inputs = [{"url": "https://www.auctions.yahoo.co.jp/product/sample-item-123456"}]
snapshot_id = trigger_collection(inputs, limit=200, notify="https://your-webhook.com/hook")
results = get_results(snapshot_id)
