Payments
x402 Facilitator
The AWE x402 Facilitator helps applications verify and settle programmatic payments between buyers and sellers.
x402 is an open payment standard built around the HTTP 402 Payment Required status code. It allows APIs, applications and agent services to charge for individual requests without requiring subscriptions or manual payment flows.
How an x402 payment works
A buyer requests a protected resource.
The server responds with
402 Payment Requiredand provides payment instructions.The buyer prepares a payment authorization and submits it with the request.
The facilitator verifies the authorization and settles the payment onchain.
Once the payment is confirmed, the server provides the requested resource.
Why use a facilitator?
Applications can verify and settle x402 payments independently. A facilitator provides this functionality as a service, reducing the blockchain infrastructure that each developer needs to operate.
The AWE Facilitator provides standard endpoints for:
Verification — Confirm that a payment authorization is valid.
Settlement — Submit the authorized payment onchain.
Status handling — Return the result to the application so it can provide the requested resource.
Current support
The AWE Facilitator currently supports fee-free USDC payments on Base, allowing sellers to receive the full payment amount without an additional facilitator fee. Standard network costs may still apply.
What builders can monetize
The facilitator can support payments for:
API requests
AI inference
MCP tools
Agent services
Digital content
Usage-based applications
AWEtoAgent Kit provides a higher-level framework for adding x402 payments to agent applications.
