Why this scraper?

🔍 Three discovery modes

Search — keyword-based product discovery across all three Walmart markets. Bulk — supply a list of item IDs directly for the fastest possible fetches, no search overhead. Monitor — track a fixed set of products and get only the items that changed since last run.

📉 Price change tracking

Every run compares current price and availability against last-known values. Each item gets a changeStatus field: NEW, PRICE_DROP, PRICE_RISE, RESTOCKED, OUT_OF_STOCK, or UNCHANGED. Enable outputOnlyChanges to emit only changed items — perfect for daily monitoring schedules.

⚠️ MAP violation detection

Supply a mapPrices object ({ "itemId": 49.99 }) and every product below its Minimum Advertised Price is flagged with mapViolation: true, mapPrice, and belowMapBy — ready to feed into MAP enforcement workflows.

📍 ZIP code geo-targeted pricing

Walmart prices and availability vary by location. Enter any US ZIP code to scrape exactly what a buyer in that area sees.

🎨 Variant pricing

Sizes, colours, and configurations — each variant's price, availability, and stock status extracted separately.

⭐ Customer reviews (add-on)

Enable includeReviews for per-product reviews: rating, text, verified-purchase flag, helpful votes. Billed at $0.50/1,000 reviews.

🌎 Three Walmart markets

walmart.com (USD), walmart.ca (CAD), walmart.com.mx (MXN) from one actor.

Known limitations

• outputOnlyChanges outputs zero items on the first run (all items are NEW, which counts as changed). Useful from the second run onwards.
• Price history is stored in the default KV store per run — it is shared within the same scheduled task but not across separate actor runs without a scheduler.
• ZIP targeting is US-only; .ca runs ignore zipCode.
• walmart.com.mx is accepted as input but currently returns limited data — the .mx site serves a different page structure that the scraper does not yet fully support. Use walmart.com or walmart.ca for reliable results. .mx support is planned for a future release.
• Review text is extracted from the product detail page — requires fetchDetails: true when using includeReviews.
