Facilitator

Defined in: src/x402/types.ts:300

A facilitator endpoint kawasekit can talk to.

Two implementations live in src/x402/facilitator.ts:

• createHttpFacilitator() — proxies /verify & /settle over HTTP to any x402 v2-compliant endpoint (Coinbase CDP, a self-hosted mirror, etc.)
• createSelfFacilitator() — runs transferWithAuthorization from a private key kawasekit holds locally (testnet / self-host case)

createX402Handler() accepts any object satisfying this interface and is agnostic to the underlying transport (HTTPS, in-process, mocked).
