facilitator
A trusted intermediary role in the x402 protocol architecture, responsible for verifying payment signatures, broadcasting transactions and bearing gas fees, so that a server can trust that payment has occurred before block confirmation.
Timeline (last 90 days)
Batch settlement is a layer used by the client and the facilitator it routes through to decide when to actually put these authorizations on-chain, and in theory does not require the endpoint to modify pricing or the challenge structure.
In the x402 ecosystem, it is often the facilitator, rather than the client itself, that actually broadcasts the payment on-chain, confirms the result and returns the credential to the seller.
In the x402 response, the feePayer field indicates that the facilitator will bear the Gas fees, so the Agent only needs to hold USDC to complete payment and does not need to maintain a SOL balance.
The marginal cost of blockchain settlement is mainly reflected in Gas fees rather than proportional commissions, and x402's facilitator model can further externalize this portion of the cost.
