Barcode
Search by barcode — Looks up a Walmart product by its UPC/EAN/ISBN barcode.
History Offers
Per-seller offer history for a product — price, stock, and seller changes over time.
History Product
Product-level price history — buy-box price snapshots over time.
Product
Get product by ID — Fetches live product data from Walmart by item ID, including pricing, availability, offers, and variants. availableQuantity is null unless stock is low; for exact stock counts use seller_offers_b2b.
Reviews
Get product reviews — Fetches paginated customer reviews for a Walmart product, including ratings, review text, photos, and helpful vote counts.
Search
Search products — Searches the Walmart catalog and returns paginated product listings with prices, ratings, and availability.
Seller Catalog
Seller product catalog — Pages through a seller's full product catalog — the storefront's "Shop all" grid — by catalog seller ID, returning up to 40 products per page with prices, ratings, and availability. Walmart hard-limits this to 25 pages per seller (25 × 40 = 1000 products), so pages beyond 25 return no further items and the page param is clamped to 25. Use seller_featured_products for the storefront's curated best-sellers and seller_page for seller identity, reviews, and contact details.
Seller Featured Products
Seller featured products — Returns a seller's featured products by catalog seller ID — the curated "Top picks" Walmart surfaces on the seller's storefront landing page. This list is compiled by Walmart's own algorithms (generally the seller's best-selling products), not chosen by the seller, and returns up to 40 products with prices, ratings, and availability. Use seller_catalog to page through the seller's full product list, and seller_page for seller identity, contact, and reviews.
Seller Offers B2b
All seller offers (B2B) — Lists every seller's offer for an item with per-fulfillment stock counts (fulfillmentOptions[].availableQuantity), prices, and delivery options. Use this endpoint for inventory/quantity questions — the product endpoint hides exact stock unless it is low. A quantity of 9999 is a sentinel meaning untracked/plenty, not a real count.
Seller Offers B2c
All seller offers (B2C) — Lists every seller's offer for an item as seen by the consumer app — prices, sellers, and delivery options. Exact stock counts are hidden on the consumer surface; for inventory/quantity use seller_offers_b2b.
Seller Page
Seller page — Returns the main seller page by catalog seller ID — the seller's identity and profile: display/legal names, Pro-seller status, customer review summary and rating breakdown, about text, and business contact details (address, phone, email). Not every seller exposes every field — contact details in particular are often withheld — so treat individual fields as optional. Use seller_featured_products for the storefront's curated best-sellers and seller_catalog to page through the seller'
Seller Statistics
Tracked-seller catalog statistics: buybox win rate, Walmart-fulfilled (WFS) rate, in-stock rate, average price, and products added/removed between daily catalog snapshots. An unknown seller is verified live: nonexistent sellers return a not-found error, existing ones start being tracked and return null fields until their first snapshot completes.
