Facilitator
Dexter's facilitator verifies payment authorizations and submits payments for settlement. A seller can use it through Dexter's x402 SDK or an existing x402 integration. The seller chooses the price, receiving address, and accepted network for each service.

Accept a Payment contains a complete Express example using Dexter's SDK. For an existing x402 server, the facilitator integration example shows how to configure HTTPFacilitatorClient.
GET /supported lists the available networks, payment schemes, and their requirements.
Use POST /verify to check a payment authorization against the seller's payment requirements.
POST /settle submits the payment and returns its settlement result.
Keep the amount, recipient, asset, and network tied to the seller's offer through verification and settlement. The SDK example returns the result with a payment receipt after successful settlement. Errors and Retries covers interrupted or rejected payments.
Choose a Network
Read the current /supported response for the scheme and network combination your service needs. Each network guide includes its identifiers and server configuration.
