Questions
Walmart’s Affiliate API, on Walmart I/O, returns product lookups with price and stock, keyword search, category catalogues and reviews. Its terms make it available to affiliate partners solely to advertise Walmart.com products, bar competitors from using it to review Walmart pricing or product availability, and cap calls at 5,000 a day. Walmart’s Marketplace APIs serve sellers and approved Solution Providers managing their own listings. For other uses, data APIs return public Walmart data with an API key.
Walmart publishes no price for its Affiliate or Marketplace APIs, but each comes with conditions: the Affiliate API is for affiliates advertising Walmart.com products, and the Marketplace APIs are for approved sellers and Solution Providers. For public product data, most data APIs let you start free: Monocrawl gives 1,000 credits every month, Bright Data 5,000 records a month, Scrape.do 1,000 credits a month and Apify $5 of usage a month. ScraperAPI has a 7-day trial with 5,000 credits and a free plan of 1,000 credits, ScrapingBee gives 1,000 free credits, Decodo a free plan with 1,000 premium requests, BlueCart and SearchApi 100 free requests, and Oxylabs a free trial of up to 909 results on sites other than Amazon and Google.
Yes, with most data APIs. Scrape.do pins every Walmart request to one store, by store ID or ZIP code. SearchApi, ScrapingBee, Oxylabs and BlueCart accept a store ID or ZIP code, Decodo takes a ZIP code as its location and Bright Data has scrapers for products by ZIP code. Monocrawl’s category call accepts a ZIP code and store ID, and its offers call lists each seller’s price and stock for an item.
Yes. Monocrawl returns product reviews ten per page with the rating distribution, and seller reviews that name the product bought. Apify’s Walmart Reviews Scraper, Bright Data’s Walmart Reviews scraper, BlueCart, ScraperAPI and SearchApi also return review text, and Walmart’s Affiliate API returns reviews for affiliates. Oxylabs, Decodo, Scrape.do and ScrapingBee return each product’s average rating and count.
Not with Monocrawl: you send your Monocrawl API key with a Walmart item ID, a search term or a category ID and get public data back, with no seller account, affiliate app or signed request. Walmart’s Marketplace APIs need an approved seller account, or Solution Provider approval that Walmart says can take three to five weeks. Its Affiliate API needs a Walmart I/O app with an uploaded public key, and each request carries a signature made with your private key.
Monocrawl, Apify, Bright Data, Decodo, ScraperAPI, ScrapingBee and SearchApi publish their own MCP servers that reach Walmart data, so assistants such as Claude or Cursor can call them directly. Oxylabs’ MCP server has no Walmart tool, but its general scraper can fetch Walmart pages.
