# Wayfair Checkout Buy, track, and return products from Wayfair (wayfair.com) through the Zinc API (`https://api.zinc.com`). US orders. > **Powered by Zinc Universal Checkout.** The same API buys from Wayfair and 50+ other US retailers (Amazon, Walmart, Target, Best Buy, eBay, and more). To order across multiple retailers from one skill, install the [`universal-checkout`](https://github.com/zincio/skills/tree/master/skills/universal-checkout) skill (`npx skills add zincio/skills --skill universal-checkout`). Live retailer list: `GET https://api.zinc.com/retailers`. ## Quick Start **Which auth method should I use?** - **`ZINC_API_KEY` env var is set** → Use `POST /orders` with Bearer token auth. This is the standard flow for pre-registered users. - **MPP — no account needed** → Use the `/agent/*` endpoints and pay per request with a **Stripe card** (via Stripe Link — no crypto), **Tempo** stablecoins, or **x402** (USDC on Base). `POST /agent/orders` to buy; `/agent/search` to discover ($0.01 per data call). `GET /retailers` is free. - **Neither is set** → Ask the user to either sign up at [app.zinc.com](https://app.zinc.com) for an API key, or set up an MPP payment method. Try it without code at [agent.zinc.com](https://agent.zinc.com). All amounts are in **US cents** (e.g. `5000` = $50.00). ## Authentication ### API Key Auth ``` Authorization: Bearer $ZINC_API_KEY ``` ### MPP Auth (Machine Payments Protocol) MPP is an open standard for HTTP 402 machine-to-machine p
