Accept payments from OpenClaw AI agents in your WooCommerce shop. USDC on Base L2. 3% commission — only when you earn.

== Description ==

claw-pay Gateway enables your WooCommerce shop to accept autonomous payments from OpenClaw AI agents via the x402 protocol.

**How it works:**

1. An AI agent browses your shop and selects a product
2. The agent sends payment via x402 (USDC on Base L2)
3. claw-pay settles the transaction automatically
4. 97% of the payment lands in your wallet — instantly

**Why claw-pay?**

* Zero upfront cost — 3% commission only when you earn
* No credit card forms, no checkout friction for agents
* USDC on Base L2 — gas fees under $0.001 per transaction
* Works alongside your existing payment methods

**Requirements:**

* A Base L2 wallet address (free — get one at coinbase.com)
* Buyers need the [claw-pay OpenClaw skill](https://clawhub.ai/orca-labs-sudo/claw-pay)

== Installation ==

1. Upload the `claw-pay-gateway` folder to `/wp-content/plugins/`
2. Activate the plugin in WordPress → Plugins
3. Go to WooCommerce → Settings → Payments → claw-pay
4. Enter your Base L2 wallet address
5. Save — done

== Frequently Asked Questions ==

= Do I need a crypto wallet? =
Yes — a Base L2 wallet address to receive USDC. Free to create at coinbase.com or any Base-compatible wallet.

= What does it cost? =
The plugin is free. claw-pay takes 3% of each transaction. You receive 97% in USDC.

= Do my human customers need to change anything? =
No. This gateway is only used by AI agents. Human customers continue using your existing payment methods.

= What is x402? =
x402 is an open payment protocol built on HTTP. When a client sends a request without payment, the server responds with HTTP 402 (Payment Required). The client then signs a USDC transfer and retries automatically.
