Use case

AI Ad Spend Agent - Control Budgets Across Platforms

Name: Agentspay
Brand: Agentspay

An agent that manages ad budgets can scale spend faster than a human can watch. Put daily and total caps on it, one card per platform, and sign-off on budget jumps.

In short

An AI ad spend agent funds and adjusts advertising campaigns across platforms like search and social. Agentspay enforces daily and total caps and issues a scoped virtual card per ad platform, so the agent cannot exceed the budget or move spend to an unapproved channel. Large budget increases above your threshold pause for human approval, and every dollar is attributed by platform and campaign in the audit trail.

The challenge

An optimizing ad agent can ramp daily budgets aggressively, so a wrong signal can multiply spend across platforms before a human reviews it.

How Agentspay handles it

Agentspay applies hard daily and total caps to the ad wallet and gives each platform its own scoped card with its own limit, so no single channel can overrun. Budget increases above your threshold are routed for one-tap approval before they take effect. The audit trail breaks spend down by platform and campaign so you can reconcile against results.

The control surfaces

The controls behind it

The surfaces this use case leans on, each enforced before any money moves.

Spend controls

AI agent spend controls are rules that limit what an agent can buy: per-transaction, daily, and total caps, merchant and category allowlists, and velocity limits. Agentspay evaluates them at the API boundary, so a hallucinating or compromised agent is declined before it can overspend, not flagged after.

Virtual cards

Virtual cards for AI agents are programmatically issued card credentials that are scoped to a single merchant, amount, and time window. The agent uses a tokenized, masked reference and never sees a raw card number, which keeps you out of PCI scope. You issue and revoke them through a virtual cards API.

Human approvals

Human in the loop agent payments means an agent's transaction pauses for human sign-off when it crosses a threshold you set. The agent waits, the request is sent to Slack, email, or a webhook, and nothing settles until a person approves or denies. The decision and approver are recorded in the audit trail.

Audit trail

An audit trail for AI agent spending is an immutable, append-only record of every payment an agent made. Each row links the spend to the intent that triggered it, the agent that requested it, the human who owns the agent, the policy verdict, and the approver. It gives you cost attribution, reconciliation, and a record you can defend.
