Scrape Walmart.com at scale: product search, category listings, full product details, every seller offer, and customer reviews. 5 operations, one clean JSON dataset. Built for price monitoring, competitor catalog mapping, marketplace seller intel and review analysis.
All notable changes to the Walmart Price Tracker & Data API will be documented in this file.
[1.1.0] — 2026-07-22
📎 Batch inputs — one run, many items
productIds, queries, categoryIds — pass a list instead of a single value and one run covers them all. The singular fields still work exactly as before; the plural ones win when filled.
One actor start per run, not per item. Monitoring 100 products used to mean 100 runs and 100 start fees; it's now one run and one. This is where the cost sits on scheduled, repeated lookups.
Blanks and duplicates are dropped automatically. Up to 500 items per run; maxPages applies per item, so the two multiply.
One item failing never aborts the batch — it lands as a status:"error" row (still free) and the run continues.
💰 Pricing
apify-actor-start cut from $0.006 to $0.0005 — a 12x reduction, putting it near the lowest start fee on the Store. Per-row prices are unchanged.
📝 Docs
Corrected the field-count claim to the measured 87 fields on a real product-details row.
Removed two claims that didn't survive checking: an unsupported user-count boast, and a per-row price comparison that isn't accurate against the current field of Walmart actors.
