Name: Agentspay
Brand: Agentspay

Agents are starting to hire other agents. When one agent pays another, you need identity, limits, and a record on both sides of the transaction.

In short

Agent to agent payments are transactions where one autonomous agent pays another for a service or result. Agentspay settles them under policy: the paying agent draws from a capped wallet, the receiving agent gets a payout into its own wallet, and both sides carry a named identity and owner. The settlement is written to a shared audit trail so the spend and the earning reconcile against each other.

The challenge

When agents transact with each other, an unidentified or unbudgeted counterparty can drain a wallet with no record of who got paid or why.

How Agentspay handles it

Agentspay attaches a named identity and human owner to every agent, so each side of a settlement is accountable. The paying agent is held to its wallet caps and policy, while the receiving agent gets earnings as a payout under the same controls. Both legs are recorded in the audit trail, giving you matching records for the payment and the payout.

AI agent wallet

Agent wallet

An AI agent wallet is a funded, budgeted account that belongs to a single agent. You top it up to a set amount, attach spend limits and rules, and the agent draws from it. Because the wallet is capped and policy-gated, the agent cannot exceed its budget or spend outside the rules you wrote.

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.

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.

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.

Frequently asked

Questions people ask about Agent-to-agent

What are agent-to-agent payments?

Agent to agent payments are transactions where one autonomous agent pays another for a service or result, with no human approving that specific transfer in the moment. Both agents still belong to a human or company owner, and both owners need a record they can reconcile afterwards.

How do AI agents pay each other?

The paying agent draws on a capped wallet or scoped instrument its owner funded, and the receiving agent takes a payout into its own wallet. Price is agreed before the work, often as a machine readable quote. Settlement writes a matching record on both sides so the spend and the earning line up.

How do you verify the identity of another AI agent?

Through a signed credential rather than a self declared name. Know Your Agent schemes bind an agent to a human or corporate owner and issue a signed token the counterparty can check before transacting. Without that binding you are trusting a string in a request header, which is not an identity.

What happens if an AI agent pays the wrong agent?

That depends entirely on the rail. Card payments can be disputed and reversed; stablecoin settlement generally cannot. This is why the practical protection is preventive: a counterparty allowlist and a per transaction cap stop the wrong payment from leaving rather than trying to claw it back afterwards.

Who is liable when one AI agent pays another?

The human or company that owns the paying agent. No jurisdiction treats an agent as a legal person, so authority flows from the owner who funded the instrument and set the policy. That is a practical argument for recording which policy allowed each payment, not just that the payment happened.

What is the A2A protocol for payments?

A2A in the agent context refers to agent to agent communication, which handles discovery and task delegation but not settlement. The specification reached version 1.0 in April 2026 under Linux Foundation governance, and our full breakdown of the A2A protocol and agent to agent payments covers what an Agent Card commits you to. Payment still needs a separate layer, whether that is HTTP 402 style per call payment, a card network agent token, or an invoice. Note that A2A also means account to account in mainstream fintech.
