Payments for autonomous agents.

Let AI agents pay during normal HTTP requests. They sign guarantees off-chain and spend against pooled collateral, so each request can be authorized without prefunding or an on-chain transaction.

Pay per request

Agents spend on credit and settle later — no balance top-ups before each call.

No gas per call

Thousands of spends batch into one on-chain settlement per cycle.

Works with x402

Add the credit scheme to the x402 clients your agents already use.

Use cases

Built for agentic commerce workflows

Give each stakeholder the payment primitives they need: instant authorization, clear limits, and settlement that stays easy to audit.

For agent builders

Let agents buy tools

Give autonomous workflows a payment method that works inside ordinary HTTP requests.

Control spend windows

Set spending limits, expiry, and settlement windows so agents can move quickly inside defined risk bounds.

Keep payments out of the way

Agents can access paid resources without wallet pop-ups or prefunding steps.

For resource providers

Accept signed guarantees

Verify every request before serving paid content, compute, data, or actions.

Settle revenue in batches

Group high-frequency agent payments into settlement cycles that are easier to reconcile.

Process

Start with agentic commerce in 3 steps

The path is deliberately small: configure the payment session, verify each request, then settle the cycle with durable records.

01
Give the agent credit
Back the agent with collateral and the spending limits, payer, recipient, and terms it can sign against.
02
Attach a payment guarantee
The agent signs each request off-chain and the provider verifies the guarantee before responding.
03
Settle the cycle on-chain
Many small agent payments become one auditable settlement against pooled collateral.

Works with the stack you already use — use 4Mica through x402-compatible HTTP clients, SDKs, any x402 facilitator, and the settlement infrastructure behind them.

FAQ

Common questions about agentic commerce

Can an AI agent pay without holding funds in its own wallet?

Yes. The agent can spend against collateral-backed credit and attach signed guarantees to requests. Final settlement happens later on-chain.

Does every agent request create a blockchain transaction?

No. Individual requests are authorized off-chain. The on-chain footprint is pushed to batched settlement windows.

How do providers know a request will be paid?

Providers verify the guarantee, payer, amount, asset, and terms before serving the resource.
