# Universal Checkout Skill

> Let AI agents buy anything with a URL using the Zinc API.

The **Universal Checkout Skill** is an [Agent Skill](https://agentskills.io) that enables AI agents to place and manage e-commerce orders through the [Zinc API](https://zinc.com). Once installed, you can ask your AI agent to buy products from online retailers, check order statuses, and list recent orders — all through natural language.

## What is an Agent Skill?

An Agent Skill is a declarative specification (a `SKILL.md` file) that teaches AI agents how to interact with an API. There's no executable code — the skill simply provides instructions, endpoint definitions, and safety guidelines that the agent follows.

Agent Skills use **progressive disclosure**: at startup only the skill name and description are loaded. The full instructions are read into context only when the agent detects a matching task, keeping your agent fast and focused.

## What Can It Do?

The Universal Checkout Skill gives your agent three capabilities:

| Capability             | Description                                               |
| ---------------------- | --------------------------------------------------------- |
| **Place orders**       | Buy products from supported retailers using a product URL |
| **Check order status** | Look up the current status and tracking info for an order |
| **List orders**        | View recent orders placed through Zinc                    |

<Warning>
  Placing an order spends real money from your Zinc account. The agent will
  always confirm with you before submitting an order.
</Warning>

## Supported Platforms

The Universal Checkout Skill works with any agent platform that supports the [Agent Skills](https://agentskills.io) standard, including:

* [OpenClaw](https://openclaw.ai)
* [Claude Code](https://claude.ai/code)
* [Gemini CLI](https://github.com/google-gemini/gemini-cli)

## Prerequisites

Before you begin, you'll need:

1. A **Zinc API key**. [Sign up at app.zinc.com](https://app.zinc.com) to get one.
2. Funds deposited in your Zinc account to place orders.
3. A supported AI agent platform (see above).
