How this service works
Search for products on Walmart with pagination support and multiple filters and options such as sort by, price range, location, and more.
Output
Returns a paginated list of Walmart products matching the query, each with title, price, currency, brand, seller, rating, product URL, image URL, shipping and pickup availability, and pre-order status. Also returns a location object confirming which store the prices were rendered for, and facet data for further filtering.
Example use cases
Budget gift shopping on Walmart
“Find me top-rated toys on Walmart under $25 sorted by best_seller — I'm shopping for a gift and want to see what's popular right now.”
Walmart Canada store-specific search
“Search Walmart Canada for 'winter boots' at store 3148 in Lévis, QC, sorted by price low to high, and show me page 1 of results.”
Price comparison research for electronics
“Look up 'iPhone 15 case' on Walmart in California, sorted by lowest price, with a max price of $20 — I want to compare what's available and in stock.”
Technical details
Endpoint
GEThttps://agents.openwebninja.com/real-time-walmart-data/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time Walmart product search results with flexible filtering by price, sort order, store location, or category facets, and need to return multiple paginated results. Prefer this over Amazon or eBay search endpoints when the user specifically wants Walmart pricing or availability, or when US/Canada store-level localization is needed.
Side effects
- Missing required 'query' parameter returns a 400 validation error
- Invalid store_id may cause Walmart to default to a different store without warning
- Price filters where min_price >= max_price will be rejected
- Unavailable products or out-of-stock items may still appear in results
- store_id is currently ignored for the 'us' domain
- Facet strings must be obtained from a prior search response; invalid facets silently drop the filter
- Rate limits or payment failures return 402 or 429 errors from the proxy
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| page | number | Page number for pagination. Default is 1. |
| facet | string | Facet filter string for refining results (e.g. by brand, category). Obtained from a previous search response's facet data. |
| queryrequired | string | Search query string. E.g. 'laptop', 'iphone 15', 'nike shoes' |
| state | string | US state code (e.g. 'CA', 'NY') to localize search results such as availability and shipping options. |
| domain | string | Walmart domain to search. 'us' for walmart.com, 'ca' for walmart.ca. Default is 'us'. |
| sort_by | string | Sort results by the given criteria. Accepts aliases: price_low, price_high, best_seller, top_rated. Default is best_match. |
| store_id | string | Walmart store ID to get store-specific prices and availability. Supported for domain 'ca': results are rendered for that walmart.ca store (e.g. '3148' for Lévis, QC) and the response `location` object confirms the store applied. Without it walmart.ca defaults to Mississauga Supercenter (store 1061). For domain 'us' this parameter is currently not applied to search results. |
| max_price | number | Maximum price filter. Must be higher than min_price if both are specified. |
| min_price | number | Minimum price filter. Must be lower than max_price if both are specified. |
