Use Cases

What Teams Build With
Walmart Data

One endpoint feeds the systems engineering teams ship to production — repricing, monitoring, sourcing, and intelligence.

Featured Offer Repricing

React to Featured Offer losses by streaming winner changes per item into your repricing engine. WFS (Walmart Fulfillment Services) listings win it roughly 3.4x more often than seller-fulfilled offers at the same price point.

Seller Intelligence

Track WFS vs. seller-fulfilled competition, ratings, and offer counts to model competitive pressure per SKU.

MAP & Brand Protection

Monitor seller identity, observed offer price, shipping, and fulfillment context across Walmart Marketplace offers.

Common Questions

Answers to Walmart-specific questions about marketplace data, sellers, and integration.

Browse all FAQs

Yes. Every offer is tagged with seller type (1P or 3P) and fulfillment method (WFS or seller-fulfilled). Your repricing logic can treat them as separate competitive sets.

Walmart's Buy Box (the 'Pro Seller' offer) is identified explicitly in each result, along with the winning price and seller. Updates stream via webhook when streaming is enabled.

Yes. Rollback status and any visible promotional pricing are exposed alongside the regular price, so your engine can react to Walmart-driven discount cycles.

Both. kwery resolves UPCs to Walmart Item IDs automatically, so your catalog can match either way without preprocessing.

Yes. Specify country: "ca" in your request to query Walmart.ca. Same schema as US, with localized currency and seller set.

Live on every request. Streaming jobs deliver each result as soon as it's collected.
