What can you build with Inventory Management?

Inventory Management 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. Inventory Management is free to use, making it a low-risk choice to experiment with.
