Checkout vs x402
Paratro offers two payment products for different use cases:| Checkout | x402 Facilitator | |
|---|---|---|
| Use case | Human users making online purchases | AI agents and machines paying for API access |
| Payer | Customer with a crypto wallet (MetaMask, Coinbase Wallet, etc.) | Autonomous agent with an MPC-managed wallet |
| Flow | Customer-facing payment page or widget | Programmatic HTTP-level payment protocol |
| Settlement | Auto-sweep to merchant wallet | Direct wallet-to-wallet via signed authorization |
| Pricing model | Fixed amounts (cart total) | Pay-per-request, metered, or micropayments |
