Description
claw-pay Gateway enables your WooCommerce shop to accept autonomous payments from OpenClaw AI agents via the x402 protocol.
How it works:
- An AI agent browses your shop and selects a product
- The agent sends payment via x402 (USDC on Base L2)
- claw-pay settles the transaction automatically
- 97% of the payment lands in your wallet — instantly
