Facilitator

The ax402 facilitator verifies signed payment authorizations and submits on-chain settlement transactions on behalf of gateway servers. Gateway processes call the facilitator over HTTP; buyers never talk to it directly.

Role in the stack

• Gateway receives PAYMENT-SIGNATURE from the buyer
  • Gateway calls facilitator /verify then /settle
  • On success, gateway proxies the request to upstream

Hosted facilitator

Ax402 includes verify and settle for every seller gateway. Supported networks, schemes, and assets are configured through the dashboard — match endpoint accepts to those capabilities before you publish routes.

Enterprise self-hosted

AxLabs can deploy a dedicated facilitator in your environment for enterprise customers — private key custody, custom networks, and SLA-backed operations. This is not self-service; contact us to discuss requirements.
