How x402 Works
1. Connect Wallet
Link your self-sovereign wallet once. AI agents act on your behalf with your approval.
2. AI Agents Pay
When an agent calls an MCP, x402 automatically settles payment in USDC on Base — no human approval needed.
3. Per-Call Billing
No credits to buy upfront, no monthly fees. Pay exactly what MCPs charge per call.
