AI agent payment control platform
Let agents transact.
Never lose control.
x402 makes payment a native HTTP action. LavoLoop adds isolated funds, budgets, permissions, human approvals, and a complete audit trail—so software can transact autonomously while people retain final control.

Our point of view
The internet learned to move information. Now it is learning to move value.
Every paid API still asks for an account, a subscription, prepaid credit, and a long-lived key. That is a commercial flow designed for people—not agents that discover a tool, compare a price, and act in the moment.
A unified payment layer is not merely a faster checkout. It lets software exchange value without establishing a commercial relationship in advance.
A unified machine payment layer
- Discover price in the request
- Standard payment terms
- Pay for actual usage
- Resource and receipt return together
- Policies execute automatically
HTTP 402, finally activated
x402 turns “payment required” into a protocol machines understand.
A server returns HTTP 402 with the price, network, asset, and recipient. The client signs a payment and retries the same request. Once verified, the resource is returned—without account creation or a pre-arranged API key.
Read the official x402 docsRequest a resource
The agent calls an API or accesses content as usual.
Receive 402
The service returns structured terms and accepted payment methods.
Check and pay
LavoLoop enforces budget and permission policy before signing.
Get the result
The service settles payment and returns the resource with a receipt.
The protocol solves payment. The control plane solves trust.
LavoLoop above x402
Being able to pay is not the same as being allowed to pay.
x402 defines how machines exchange value. LavoLoop decides which agent can pay whom, how much, for which task, and when a human must intervene.
Isolated funds
Agents can access their own balance, never your primary wallet.
Hard budgets
Daily or monthly ceilings stop spending at the boundary—not after it.
Service permissions
Restrict services, networks, and maximum payment amounts.
Human approvals
Risky or over-threshold requests pause before money moves.
Idempotent execution
Retries never turn one request into duplicate charges.
Complete audit trail
Every payment retains agent, task, service, and settlement context.
Not a waitlist
The control plane already exists. See how autonomous spend is constrained.
Create agents, configure budgets, initiate x402 payments, resolve approvals, and inspect persistent transaction records in a test environment. This is a working payment control plane, not a concept render.

One rail, three participants
When payment becomes a protocol, the product surface expands.
Agent builders
Let agents buy search, browsing, models, data, and compute on demand without maintaining an account for every service.
API and content sellers
Turn an endpoint into a pay-per-use product that machine customers can purchase on the first request.
Teams and platforms
Create a clear boundary between automation speed and financial control, with an owner and rationale for every machine expense.
x402 and agent payment FAQ
Start with the important questions.
01What is x402?+
x402 is an open standard for internet-native payments built around HTTP 402 Payment Required. It lets APIs, websites, and agents negotiate and complete payment inside standard HTTP requests.
02Why do AI agents need a unified payment method?+
Agents select services dynamically. Account registration, subscriptions, and manual API-key provisioning cannot match that speed. A shared protocol makes discovery, authorization, payment, and delivery programmable.
03How is LavoLoop different from x402?+
x402 is the payment protocol. LavoLoop is the buyer-side control plane that manages funds, agent identity, budgets, service permissions, approvals, and audit history.
04Can an agent spend without limits?+
No. LavoLoop enforces hard budgets and service policy before signing. Requests above a threshold pause for a human decision.
05Does the current console move real money?+
The public console currently runs on Base Sepolia in test mode. It demonstrates the complete payment, approval, and audit flow without moving production funds.
