Endpoint
GEThttps://agents.openwebninja.com/real-time-walmart-data/product-offers?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive view of all seller offers for a specific Walmart product, including marketplace sellers, shipping options, and return policies. Prefer this over a general product details endpoint when price comparison across sellers or seller vetting is the primary goal. Choose this when you need to surface the best deal, lowest price, or most favorable return policy among multiple Walmart sellers for a single product.

Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| domain | string | Walmart domain. 'us' for walmart.com, 'ca' for walmart.ca. Default is 'us'. |
| store_id | string | Walmart store ID to get store-specific offers and prices. Supported for domain 'ca': the product page is 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). Not applied for domain 'us'. |
| product_idrequired | string | Walmart product ID. For domain 'us' this can be the numeric us_item_id (e.g. '609040889') or the alphanumeric product_id (e.g. '4SZSM8SXAAJT'). For domain 'ca' use the `us_item_id` value returned by search (e.g. '875806'), not the numeric internal `product_id`. |
