What can you build with Catalog API?

Catalog API is a Commerce API. Developers commonly use commerce APIs for:

  • syncing product catalogues and inventory levels
  • building price comparison and deal-finder tools
  • processing orders and tracking shipments
  • managing customer wishlists and reviews
  • automating abandoned-cart and promotional emails

No authentication required. This API is open — no signup or key needed. Ideal for quick prototypes and public-facing features. Catalog API is free to use, making it a low-risk choice to experiment with.
