Technical details
Endpoint
POSThttps://serp402.com/api/v1/walmart-product-reviews?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, machine-readable Walmart customer review data for a specific product — especially useful for e-commerce analytics, sentiment analysis, price-comparison tools, or reseller research. Prefer this over manual scraping when you need paginated or rating-filtered results without managing Walmart's anti-bot measures. Best suited for workflows that already have a Walmart us_item_id (e.g. from an Organic Results API call).
Side effects
- Invalid or non-existent product_id returns empty results or an error
- Invalid sort parameter value may return an error or default sort
- Invalid rating filter value may cause an error or return unfiltered results
- Page number beyond available pages returns empty review list
- Payment failure (insufficient USDC balance) blocks the request
- Rate limiting or upstream Walmart blocking may cause timeouts
