Zinc provides an API infrastructure that allows businesses to search product catalogs, place orders, and manage returns across various retailers, including Amazon and Walmart. Developers can use the tool to handle the checkout process programmatically rather than building individual integrations for each store.
The service is designed for developers building automated shopping experiences, such as AI agents, rewards programs, or curated marketplaces. It supports product metadata, variant mapping, and shipment tracking.
Buyers should confirm their funding preference, as Zinc supports both a prefunded wallet system and the use of their own retailer accounts. It is recommended to verify specific retailer availability via the Zinc status page.
