Give agents a built-in way to pay.

Register the credit scheme once, and agents can pay for APIs, tools, and data through normal HTTP requests. They spend against the operator's collateral and within the limits the operator sets.

One integration for every agent

Register the scheme in your HTTP layer, and each agent can pay without its own wallet or funding step.

Operator-controlled budgets

Set limits by request, task, seller, asset, or time window, and require approval above a threshold.

Payment records by task

Each payment includes a request ID and certificate, so you can trace it back to the task that caused it.

Use cases

Built for agent frameworks workflows

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

For framework maintainers

Make payments a built-in feature

Support paid tools in the framework instead of asking each user to build their own payment flow.

Keep your current HTTP client

The credit scheme wraps the client your framework already uses. A 402 response becomes a signed retry.

For teams running agents

Use one collateral position

One collateral position can back payments across services instead of keeping a balance with each provider.

Stop spending quickly

Pause signing, lower budgets, block a seller, or rotate credentials without changing agent code.

Reconcile by task

Group payments by task ID to see the cost of each run and the services it used.

Process

Start with agent frameworks in 3 steps

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

  1. 01

    Register the scheme

    Add the 4mica-credit client adapter to the fetch or HTTP layer your framework hands to agents.

  2. 02

    Set the operator's limits

    Back the account with collateral and define the budgets and approval rules agents run inside.

  3. 03

    Let agents pay

    Each 402 response becomes a signed guarantee and retry. The payment then joins the operator's next clearing cycle.

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

Buyer quick start

Give an agent spending power with limits, visibility, and payment proof.

Budgets and spending limits

Control how much an agent can spend, when it needs approval, and when it must stop.

Automatic paid requests

Turn 402 responses into automatic paid retries from the client you already use.

FAQ

Common questions about agent frameworks

Is an individual AI agent a 4Mica customer?

No. The customer is whoever operates the agent — the framework, the platform, or the team running it. That operator holds the collateral, sets the limits, and carries the commercial relationship. The agent is the end user that spends inside those limits, which is why there is no signup flow aimed at agents themselves.

Does each agent need its own wallet and funding?

No. Agents sign against credit backed by the operator's collateral position, so adding an agent does not mean funding another balance.

How do we cap what an agent can spend?

Set limits per request, task, seller, category, asset, network, or time window, and require manual approval for high-value payments or unfamiliar sellers.

What happens when an agent misbehaves?

Pause execution, disable signing, remove sellers, lower budgets, or rotate credentials. Check for open guarantees before withdrawing collateral so nothing is settled against a position you are unwinding.
