Always review a site's robots.txt and Terms of Service before scraping. ## TL;DR Scrape Rakuten's public product listings using AlterLab's API with automatic anti-bot handling. Start at T1 tier and let the API promote automatically if needed. Extract structured data via CSS selectors or Cortex AI for JSON output. Respect rate limits and robots.txt. ## Why collect e-commerce data from Rakuten? Rakuten hosts millions of product listings across electronics, fashion, and home goods. Engineers scrape this public data for: - **Price monitoring**: Track competitor pricing fluctuations across categories - **Market research**: Analyze product availability and description trends - **Data enrichment**: Supplement internal catalogs with public attributes like ratings and specifications ## Technical challenges Rakuten implements standard e-commerce anti-bot measures including rate limiting, header validation, and JavaScript challenges. Raw HTTP requests often fail with 403 or 429 responses. AlterLab's [Smart Rendering API](/smart-rendering-api) handles these through: - Automatic proxy rotation with residential IPs - Header normalization to mimic real browsers - Tiered rendering (from curl to full browser) based on challenge detection - JavaScript execution for dynamic content loading ## Quick start with AlterLab API See the [Getting started guide](/docs/quickstart/installation) for SDK installation. Below are examples for scraping a public Rakuten product page. Python example: ```python title="scrape_rakuten-com.py" {3-5} import alterlab client = alterlab.Client("YOUR_API_KEY") response = client.scrape("https://rakuten.com/product/example") print(response.text) ``` Node.js example (MUST include this): ```javascript title="scrape_rakuten-com.js" {3-5} import { AlterLab } from "alterlab"; const client = new AlterLab({ apiKey: "YOUR_API_KEY" }); const response = await client.scrape("https://rakuten.com/product/example"); console.log(response.text); ``` cURL example: ```bash title="Terminal" curl -X POST https://api.alterlab.io/v1/scrape \ -H "X-API-Key: YOUR_KEY" \ -d '{"url": "https://rakuten.com/product/example"}' ``` 1. **Initialize Client** — 2. **Make Request** — 3. **Handle Response** — ## Extracting structured data Rakuten product pages follow consistent HTML patterns. Use browser dev tools to identify selectors for: - Product title: `h1.product-title` - Price: `.price-current` - Rating: `.rating-value` - Description: `#product-description` Example Python extraction: ```python title="extract_selectors.py" import alterlab from parsel import Selector client = alterlab.Client("YOUR_API_KEY") html = client.scrape("https://rakuten.com/product/example").text selector = Selector(text=html) data = { "title": selector.css("h1.product-title::text").get(), "price": selector.css(".price-current::text").get(), "rating": selector.css(".rating-value::text").get(), "description": selector.css("#product-description::text").get() } print(data) ``` ## Structured JSON extraction with Cortex For schema-defined output without CSS selectors, use AlterLab's Cortex AI extraction. Define a JSON schema for typed results: ```python title="extract_rakuten-com_structured.py" import alterlab client = alterlab.Client("YOUR_API_KEY") result = client.extract( url="https://rakuten.com/product/example", schema={ "type": "object", "properties": { "title": {"type": "string"}, "price": {"type": "number"}, "rating": {"type": "number"}, "description": {"type": "string"} } } ) print(result.data) # Typed JSON output ``` Cortex handles: - Automatic type conversion (strings to numbers) - Missing field null handling - Multi-language text normalization - Unit standardization (e.g., converting "¥1,200" to 1200) - **99.2%** — Success Rate - **1.2s** — Avg Response - **$0.002** — Per Request (T3) ## Cost breakdown AlterLab's pricing scales with rendering complexity. Rakuten typically requires T2-T3 tiers due to anti-bot measures. See [AlterLab pricing](/pricing) for full details. | Tier | Use Case | Cost per Request | Cost per 1,000 | Requests per $1 | |------|----------|-----------------|----------------|------------------| | T1 — Curl | Static HTML, no JS needed | $0.0002 | $0.20 | 5,000 | | T2 — HTTP | Standard pages with headers | $0.0003 | $0.30 | 3,333 | | T3 — Stealth | Protected pages, anti-bot active | $0.002 | $2.00 | 500 | | T4 — Browser | Full JS rendering required | $0.004 ## Frequently Asked Questions ### Is it legal to scrape rakuten? Scraping publicly accessible data is generally legal under precedents like hiQ v. LinkedIn, but you must review Rakuten's robots.txt and Terms of Service, implement rate limiting, and avoid scraping private or personal data. Always comply with the site's policies. ### What are the technical challenges of scraping rakuten? Rakuten employs standard anti-bot protections that may block simple HTTP requests. AlterLab handles these via automatic tier escalation, proxy rotation, and headless browser rendering when needed, ensuring compliant access to public data. ### How much does it cost to scrape rakuten at scale? Costs start at $0.0002 per request for static pages (T1) and go up to $0.004 per request for full browser rendering (T4). AlterLab's auto-escalation means you only pay for the tier that successfully retrieves the data, optimizing costs. ## Related - [Rate My Professors Data API: Extract Structured JSON in 2026]() - [Crexi Data API: Extract Structured JSON in 2026]() - [How to Scrape Shopee Data: Complete Guide for 2026]()
