Could you build this?
Partial A Chrome extension UI that calculates margins is simple, but extracting reliable Walmart product data, Buy Box owners, and historical pricing requires scraping or expensive third-party retail APIs.
What it would actually take: The client is a Manifest V3 Chrome extension. The primary technical hurdle is extracting Walmart product data, inventory counts, and Buy Box ownership, which requires reverse-engineering Walmart's internal endpoints, bypassing Akamai/PerimeterX bot detection, or maintaining a fleet of rotating residential proxies with a data extraction pipeline.
