AI shopping agents are starting to buy things on behalf of the people and businesses that run them — and most WooCommerce stores have no way to sell to them. x402 Agent Checkout for WooCommerce fixes that: it lets compatible AI agents discover your products and pay for them directly in USDC, using the open x402 protocol, for a one-time price of $104 USD (one-time purchase). This guide walks through what it does, how it works, and everything you need to get started.
What Is x402 Agent Checkout for WooCommerce?
It’s a WooCommerce plugin built specifically for agent-to-store commerce — not a “Pay with Crypto” button for human shoppers. An AI agent finds your store, reads a machine-readable product catalog, and completes a purchase over a standard HTTP 402 Payment Required flow. No customer account, no API key issued to the buyer, no browser session — just a signed payment authorization that settles on-chain and creates a normal WooCommerce order within seconds.
Settlement runs through Coinbase’s Developer Platform (CDP) Facilitator, so you never run a blockchain node, manage private keys, or deploy a smart contract.
Key Features
- Machine-readable product catalog, filterable by search term, category, and price
- Full 402 → Verify → Settle payment flow via the Coinbase CDP Facilitator
- Single-item or full multi-item cart checkout in one order and one payment
- Full support for variable products, priced and stocked per variation
- Automatic currency conversion — non-USD stores are converted to USD before an agent is ever charged
- Optional real-time WooCommerce tax and shipping calculation
- Idempotent replay protection, so a retried payment never creates a duplicate order
- Atomic stock reservation at settlement time, preventing overselling low-stock items
- Per-IP rate limiting on the checkout endpoint
- Order status lookup for agents, using nothing but the paying wallet address
- Built-in storefront discovery — a manifest, link tags, and an HTTP header so agents can find your store on their own
- Optional automatic listing in Coinbase’s own Bazaar agent marketplace
- Settings export/import, and a dedicated payment-details panel on every order
How the Payment Flow Works
- An agent requests checkout for one or more products and receives an HTTP 402 response describing the price, network, and payment destination.
- The agent authorizes payment from its own USDC wallet and resubmits the request with a signed payment header.
- The plugin verifies and settles the payment through the Coinbase CDP Facilitator.
- The moment settlement succeeds, a standard WooCommerce order is created automatically — stock decrements, your normal notifications fire, and it shows up in your Orders list like any other sale.
What You’ll Need Before You Start
- WordPress 6.0 or higher
- WooCommerce 6.0 or higher
- PHP 7.4 or higher
- A free Coinbase Developer Platform (CDP) account
- A wallet address to receive USDC on the Base network
Setup itself is a five-minute job: install the plugin, drop in your CDP credentials and receiving wallet address under WooCommerce → x402 Agent Checkout, and enable the products you want agents to be able to buy. The plugin ships configured for Base Sepolia (testnet) by default, so you can test the full flow with free test funds before switching to mainnet.

How much does x402 Agent Checkout for WooCommerce cost?
x402 Agent Checkout for WooCommerce is $104 USD (one-time purchase). That one payment covers the plugin itself, and verifying your license after purchase unlocks ongoing support and future updates.
Is this compatible with my WooCommerce store?
It’s built for WordPress 6.0 or higher, WooCommerce 6.0 or higher, and PHP 7.4 or higher. It works alongside your existing theme and payment gateways, and supports both digital and physical products.
What do I need to set this up?
A free Coinbase Developer Platform (CDP) account and a wallet address to receive USDC on Base. You don’t need to run a blockchain node, manage private keys, or have any prior crypto experience — the plugin and Coinbase’s facilitator handle settlement for you.
Is it secure?
Payments settle through Coinbase’s CDP Facilitator using signed, verifiable authorizations, and no private keys are ever stored on your WordPress site. The plugin includes idempotent replay protection so a retried payment can’t create a duplicate order, and rate limiting to slow down abuse on the checkout endpoint.
Can an AI agent buy more than one product in a single order?
Yes. An agent can check out a full cart of multiple products, or multiple variations of the same product, in a single order and a single payment.
Does this replace my normal WooCommerce checkout for human customers?
No. It runs alongside your existing checkout and payment gateways. Agent checkout uses its own dedicated endpoint, and your regular human customers won’t see any change.
