Shopify Stores Dataset API
Product catalogs, pricing, and store information from millions of Shopify-powered online stores.
Available Data
Here's what you can extract from Shopify Stores using AlterLab:
Business Use Cases
How businesses use Shopify Stores data to make better decisions:
- Competitor product catalog monitoring
- Price comparison across stores
- Market trend analysis from new product launches
- Supply chain intelligence
How It Works
Identify your target Shopify stores
Provide the domain of any Shopify-powered store. Most Shopify stores expose a /products.json endpoint (e.g., storename.com/products.json) that returns the complete product catalog — no page rendering required for this endpoint.
AlterLab retrieves the product catalog
For stores with the /products.json endpoint, AlterLab returns the complete structured catalog in one request. For stores with additional protection, AlterLab renders individual product pages to extract all variant, pricing, and inventory data.
Get the complete product catalog
Receive product names, prices, all variants (sizes, colors), inventory quantities, images, and collection assignments for every product in the store — ready to load into your competitive intelligence system.
Key Insight
Most Shopify stores expose their complete product catalog via /products.json without any authentication. This endpoint returns structured JSON with prices, variants, and inventory levels for every product — it is often faster and more complete than page-by-page extraction.
Data Freshness
Shopify product catalogs change when merchants add products or update prices. Daily collection is sufficient for competitive monitoring. For fast-moving inventory or flash sales, hourly checks are recommended.
