The thing you can't get anywhere else

Most Walmart tools return the buy-box seller and stop. That's one price out of many.

Seller Offers returns the whole list. For a single coffee maker that's 25 different sellers, each with their own price, shipping promise, condition and return policy. That's the difference between "this product costs $179.99" and "this product costs between $179.99 and $284.00 depending on who you buy from, and here's who's cheapest today."

Useful for:

• Buy-box tracking — who owns it, at what price, and who's about to undercut them
• Reseller monitoring — find every storefront carrying your SKU
• MAP enforcement — spot sellers breaking minimum advertised price
• Competitive pricing — the whole price spread across sellers, rather than the headline price alone

Reviews carry a second bonus: Walmart's aspect sentiment — pre-computed themes like "Value For Money", "Battery Life", "Ease Of Use" with how many reviewers mentioned each. Ready-made voice-of-customer analysis with no NLP on your side.

Quick start

Find every seller for a product

{ "operation": "productOffers", "productId": "13368266581" }

Search a keyword

{ "operation": "search", "query": "coffee maker", "maxPages": 3 }

Enrich a list of products

{ "operation": "productDetails", "productIds": ["13368266581", "609040889"] }

Pull reviews with sentiment

{ "operation": "productReviews", "productId": "609040889", "reviewPages": 5 }

Where do I find a Product ID? It's the number at the end of a Walmart product URL. In walmart.com/ip/Keurig-K-Duo/13368266581 the id is 13368266581.

Bulk mode saves you money

Every input accepts a list — queries, categoryIds, productIds — up to 500 items.

One run with 100 product IDs costs one start fee. A hundred separate runs cost a hundred. Same data, a fraction of the bill.

---

Output

One flat row per result, ready for a spreadsheet or a database. Product rows carry identity (usItemId, brand, model, upc), pricing (price, listPrice, savingsAmount), ratings, seller, fulfilment, returns and media. Offer rows carry the seller, their price, condition, shipping and return terms. Review rows carry the text, rating, author, date and verified-purchase flag.

Every row is stamped with _operation and _fetchedAt so merged datasets stay auditable.

---

Pricing

Pay per result. You are charged for rows actually delivered — failed lookups cost nothing.

There's a small per-run start fee, so batching many items into one run is always cheaper than many single-item runs.

---

Notes

• One operation per run. Pick the operation, give it its inputs, get one clean dataset.
• Free plan runs are capped at 25 rows so you can try it before paying.
• Prices and availability are US Walmart. Set a Store ID to localise price and pickup.
• Built-in failover. If a lookup can't be completed the normal way, the Actor automatically retries it through a licensed backup data source rather than handing you an empty row. Rows that came from it are flagged with _backup so you always know where a row came from. You are never charged twice for the same row, and the price is the same either way.
