The Walmart Open APIs provide developers with access to Walmart.com's product catalogue information and enable affiliates to earn money through customer referrals. The Data Feed and Special Feeds APIs allow developers to get lists or feeds of products by category. The taxonomy used to categorize items can be exposed via the Taxonomy API. Developers can use the Search API to perform a text search for items on Walmart.com or use the Product Lookup API to get a specific item's price and availability. The Walmart Open APIs are currently in Beta.
