Audit trail
In short
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.
How it works
What Audit trail gives you
Intent to policy attribution
Every row answers who, what, why, and under which rule, so there is no spend you cannot explain.
Immutable and exportable
Records cannot be edited after the fact. Export to your warehouse or pull them through the audit API for reconciliation.
Cost attribution built in
Slice spend by agent, owner, vendor, or intent to see exactly where your agent budget goes.
It is one surface in the flow. Audit trail works alongside the other control surfaces so every agent transaction is checked against policy before any money moves. See the full picture on how it works and the security page.

Frequently asked
Questions people ask about Audit trail
What should an AI agent audit trail record?
Six things per transaction: the agent identity, the human who owns that agent, the intent or task that triggered the spend, the policy verdict and which rule applied, the approver if one was required, and what actually settled. Anything less and you cannot answer why a charge happened months later.
How do you reconcile AI agent spending?
Match settled transactions back to the intent that requested them rather than to a card statement line. Card statements tell you a merchant was paid; they do not say which agent or task caused it. Exporting the audit trail to your warehouse lets finance slice spend by agent, owner, and vendor directly.
Why does the audit trail need to be immutable?
Because an editable log is not evidence. If a record can be changed after a disputed purchase, it cannot settle the dispute. Append-only records mean the version you read during an investigation is the version written at authorization time, which is what makes the trail defensible to auditors and to your own finance team.
Can you attribute agent spending back to a specific task?
Yes, if the intent is captured at authorization rather than reconstructed later. Every Agentspay record links the payment to the request that triggered it, so cost attribution by agent, owner, vendor, or intent is a query rather than an investigation. That is also what makes per-agent unit economics measurable.

AI agent wallet
Agent wallet
A wallet is the unit of trust for agent money. Give each agent its own funded wallet with a hard budget, and it can only ever spend what is inside, never your full balance.
ExploreSpend controls
Spend controls
Spend controls are what stop a runaway agent. Set caps, allowlists, and velocity rules once, and Agentspay enforces them on every transaction before any money moves.
ExploreHuman approvals
Human approvals
For the spend that matters, you want a person in the loop. Set a threshold and any transaction above it is held for a one-tap approve or deny before it settles.
ExploreVirtual cards
Virtual cards
Hand an agent a card, not your card. Agentspay issues scoped virtual cards that are merchant-locked, single-use, and time-bound, so a leaked number is worthless beyond its scope.
