Known Limitations

• Prices may appear as null for some products. Kakaku.com renders certain price elements via JavaScript, which may not be captured by HTML-only scraping. In such cases, lowestPrice and priceRange will be null.
• Search results depend on kakaku.com's internal algorithm. The number of results returned may be less than maxItems if the search query yields fewer matches.
• Category structures change. Category URLs are subject to change by kakaku.com without notice. Always verify the URL before running the Actor.
• Anti-bot measures. Kakaku.com may occasionally block requests. If you experience consistent failures, try reducing maxItems or running at off-peak hours.
