About

x402 turns an API or digital service into a paid resource, so a buyer sees the price, pays and gets access within the same request flow. The CDP Facilitator verifies and settles these payments, and sellers can receive funds at any address they control. Buyers can pay from a CDP wallet or another signer.

Use cases: payments-billing
