Our take: Choose Zinc if you are a developer or AI-agent builder who wants one API to search, buy, track and return products across many retailers, paying about $1 per successful order.
Main limitation: Wallet must be prefunded with processing fees on top-ups (card 2.9% + $0.30), and volume discounts start only around 1,000 orders per month.
Who should use Zinc
Choose Zinc if you are a developer or AI-agent builder who wants one API to search, buy, track and return products across many retailers, paying about $1 per successful order. Based on the vendor's documentation, not on a hands-on test.
Best for: Developers building agentic commerce
Also a good fit for
- Businesses automating procurement
- Marketplace and rewards platforms
Consider another tool if requires prefunding a wallet; card top-ups carry a 2.9% + $0.30 fee
Or if
- Add-on fees: $0.25 for tracking links/emails, $0.10 per item over 10
- Developer-oriented; no end-user app

What is Zinc, and how does it work?
Zinc is an API covering the online purchasing lifecycle: product discovery with live retailer data, order placement, shipment tracking and returns across retailers such as Amazon, Walmart, Target, Etsy and Shopify stores. You send a product URL, an address and a price cap; Zinc handles checkout and returns an order ID. It has a dedicated setup for AI agents, including an MCP server, agent sandbox with test keys, and machine payments via x402/MPP (USDC on Solana, Base or Tempo, or fiat via Stripe). Purchases are funded from a prefunded Zinc Wallet managed in the web dashboard.
