Zinc

Zinc is an API that lets you programmatically buy anything online. Instead of building separate integrations for Amazon, Walmart, Target, Costco, and hundreds of other retailers, you connect to Zinc once. It handles the entire purchasing lifecycle: product discovery, ordering, tracking, and returns. You send a product URL, a shipping address, and a price cap, and Zinc takes care of checkout — handing back an order ID in seconds.

How does it work? Zinc provides live product data straight from the retailer — images, prices, weight, ratings, and stock levels — at the moment you ask. You can search by keyword across multiple stores at once and compare offers from different sellers by price, shipping speed, and reputation. The API supports multiple retailer accounts, so you can use your existing negotiated pricing. It's built for scale: one call can search thousands of products, and another can place an order. The system also handles tracking and returns, making it a full lifecycle solution.

Who is Zinc for? Developers building apps that need to automate purchasing — for example, AI agents that buy products on behalf of users, dropshipping platforms that need to fulfill orders, or businesses automating procurement. It's also useful for anyone who wants to build a shopping experience without dealing with each retailer's quirks. Real-world use cases include automated gift sending, scaling a dropshipping operation, and streamlining corporate procurement.
