Frequently Asked Questions
Can I extract product images and media?
Yes. The API extracts image URLs, video embeds, and media gallery data. You receive direct URLs to product images that you can download and store in your own system.
How do I handle products with multiple variants?
AlterLab renders JavaScript to capture variant selectors (size, color, etc.) and can extract all variant combinations with their individual prices and availability status.
