What is Zinc?
Zinc's official website describes itself as an API that covers the entire e-commerce procurement lifecycle, from product discovery and ordering to tracking and returns, serving thousands of retailers. The website positions it for three types of users: enabling agents to purchase over 500 million products, helping developers build cross-site shoppable applications, and automating procurement processes for enterprises. The official website also provides current homepage data, stating that 21,941,904 orders have been completed through Zinc.
Who is it for?
- Application developers who need to provide search, purchase, tracking and return capabilities for agents.
- Teams that build products for purchasing agency, price-comparison ordering, automatic gift fulfillment, or procurement automation.
- Engineering teams that want to aggregate orders and logistics status from multiple retailers into their own systems.
- Platform teams that need to simulate out-of-stock situations, price fluctuations, and address exceptions in a sandbox environment before going live.
- Enterprises that already have retailer accounts and commercial prices and wish to automate repeat purchases.
Key features
6Cross-store Product Search
The official website states that a single keyword query can simultaneously reach Amazon, Walmart, Target, Etsy, and Shopify stores, returning structured results ready for purchase, including price, images, brand, specifications, and variants.
Real-time Product Data
The official website states that prices, inventory, weight, ratings and images are read at the time of the request, rather than relying on a directory refreshed last week; it also allows comparison of prices, delivery speeds, condition and reputation across different sellers.
Unified Checkout API
The official website states that developers only need to submit the product URL, shipping address, and price cap, and Zinc will handle checkout and return the order ID. You can choose to use Zinc's retailer account or bring in an account with pre-negotiated prices.
Order Tracking and Returns
The official website states that it compiles retailer emails, carrier scan information, and delivery photos into a unified timeline, and supports programmatically generating return labels and initiating returns.
Event and Branded Notifications
The official website provides webhooks for order start, cancellation, failure, shipment and delivery, etc. It is also stated that delivery updates can be sent under your own brand, accompanied by a hosted tracking page.
Agent and Developer Onboarding
The official website and documentation list MCP Server, Agent Sandbox, Agent Skills, and TypeScript & Python SDKs; the Quick Start section shows the request method for creating an order using an API key.
How to use Zinc
- First test order creation, out-of-stock scenarios, price fluctuations, and abnormal addresses in sandbox mode, and ensure your application can handle failures and retries before proceeding to real transactions.
- For the checkout API, be sure to set a price cap and perform verification of delivery information.
- for autonomous purchasing agents, incorporate amount thresholds, product scopes, and manual confirmation rules into the product logic.
- Use webhooks as the entry point for status synchronization to avoid polling.
- at the same time, retain the operational processing workflow for failed orders, such as payment failures, exhausted retries, or merchant cancellations.
- When using your own retailer account, first confirm the platform terms, account security, tax and after-sales responsibilities.
- for cross-regional sales, also verify delivery, customs clearance and consumer return and exchange rules.
- Manage API keys and funding account permissions carefully.
- The official quick start explicitly reminds users not to share client tokens publicly.
