Agentic commerce · x402 × AiFi
Payment transport is not financial authority.
x402 gives agents and services a standard way to request, authorize, verify, and settle payment for an internet resource. AiFi is the larger operating problem: who may spend, under which mandate, within what budget, and with what evidence after settlement.
Definition boundary. ARM Agency uses AiFi here as a category label for governed AI-native financial operations. It does not imply affiliation with any AiFi-branded company, product, or institute.
The agentic commerce stack
2. x402 transport
Exchange payment requirements and signed authorization; verify and settle through supported scheme/network pairs.
3. Fulfillment
Release the paid resource once, preserve correlation, and fail safely across retries or uncertain settlement.
4. AiFi control
Reconcile intent, authorization, execution, settlement, result, exception handling, and aggregate budget.
What x402 handles
The x402 v2 specification defines core payment types, scheme logic, facilitator verification and settlement interfaces, and transport representations for paid resources. For HTTP, a resource server signals payment requirements, a client supplies signed payment authorization, and the resource is returned after successful verification and settlement.
It does not choose an agent's budget, determine an approved vendor, replace financial controls, guarantee fulfillment quality, or decide how an organization handles disputes and exceptions.
What production AiFi must control
- Signing authority stays outside prompts and browser-visible code.
- Assets, networks, recipients, resources, per-call limits, and aggregate budgets are enforced deterministically.
- Intent, policy approval, attempted action, settlement, and delivered result remain separate states.
- Retries are idempotent across payment and fulfillment.
- Named owners can freeze spending, reconcile records, and handle insufficient funds, stale quotes, compromised credentials, refunds, disputes, and chain or facilitator outages.
