Walmart Data Extraction
Extract publicly available data from Walmart at scale using AlterLab's API — JavaScript rendering, structured extraction, and automatic retries in one request.
Website Compatibility Notes
Walmart uses advanced JavaScript challenge systems with sophisticated browser fingerprinting. Product pages require full browser rendering — static requests consistently return challenge pages. The checkout and cart systems are heavily protected, but product detail and search pages respond to full browser environments. Walmart also applies geographic restrictions based on IP, so using US-based residential proxies is important for complete data access.
Technical Context
Walmart product URLs contain item numbers (/ip/{item_id}). Product pages are React-based with server-side rendering for SEO — this means the base HTML contains some product data, but pricing and availability load asynchronously. Walmart's category pages use infinite scroll. Walmart Marketplace listings (sold by third-party sellers) are mixed with Walmart's own inventory and distinguishable by the seller name field.

How do I extract Walmart product data?
Send the Walmart product URL to AlterLab with JavaScript rendering enabled. AlterLab handles Walmart's challenge pages automatically and returns product titles, prices, availability, ratings, and seller information.
Can I extract Walmart search results?
Yes. AlterLab renders Walmart search pages and returns product listings with names, prices, ratings, and availability status for each result.
What makes Walmart extraction challenging?

How do I tell if a Walmart listing is sold by Walmart or a third-party seller?
Walmart marketplace listings include a 'Sold by {seller name}' indicator on the product page. When rendered by AlterLab, this seller information is included in the page content and identifiable by its position relative to the Add to Cart button.
