Technical details
Endpoint
POSThttps://serp402.com/api/v1/walmart-product-sellers?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to enumerate all marketplace sellers for a specific Walmart product by its us_item_id, especially for price comparison, competitive analysis, or inventory sourcing. It is particularly valuable when you want to filter seller results to a specific physical Walmart store. Prefer this over general Walmart search APIs when you already know the product ID and want seller-level detail rather than product discovery.
Side effects

- Invalid store_id may return no results or an error response
- Product with no third-party sellers returns empty seller array
- Walmart product page changes may temporarily break scraping
- Rate limiting or upstream Walmart blocks may cause failures
- Missing required product_id field results in a validation error
