Shopify Store Price Monitoring API
Track prices and stock levels across independent Shopify storefronts — useful for brands monitoring their own retail partners' pricing compliance (MAP monitoring) or researchers tracking DTC brand pricing strategy.
How the Shopify Store Price Monitoring API Workflow Works
Most Shopify storefronts expose a public products.json endpoint (e.g. store.com/products.json) that returns the full catalog in structured JSON without needing to render or parse HTML at all — this is the fastest path when the storefront hasn't disabled it. For stores that have restricted or customized this endpoint, fall back to rendering individual product pages. Because Shopify is a platform used by tens of thousands of independent stores rather than a single monolithic site, difficulty varies per store — most resolve at the cheapest tier via the JSON endpoint.
Recommended Tier & Cost
Most Shopify stores expose the products.json endpoint publicly, returning structured catalog data server-side with no JavaScript rendering needed — this is why Shopify's difficulty rating is among the lowest of any e-commerce platform in AlterLab's domain guides.

How do I monitor a specific Shopify store's MAP compliance?
Pull that store's products.json endpoint on a recurring schedule and compare each SKU's variant price against your minimum advertised price list to flag violations automatically.
Does this work for any Shopify store, or only ones on myshopify.com domains?
It works for stores on custom domains too — most Shopify stores expose the same /products.json path regardless of whether they're using a myshopify.com subdomain or a custom domain.
What if a store has disabled the products.json endpoint?
AlterLab falls back to rendering individual product pages directly, extracting the same price and inventory fields from the rendered HTML instead of the JSON endpoint.
