AI Agents Need Wallets — How Virtual Cards Unlock Autonomous Commerce

Why AI agents need programmatic wallets and virtual cards to transact safely with real-time controls, audit trails, and policy enforcement.

The next wave of software runs itself. But the moment your AI agent tries to pay for an API, cloud resource, or SaaS seat, it hits a hard wall: traditional finance wasn’t built for autonomous systems.

Why agents need wallets

  • Ability to hold value, send/receive funds
  • Deterministic, API-driven behavior
  • Transparent audit trails for every transaction
  • Programmatic permissions, limits, and revocation

A wallet gives your agent an identity and balance. On top of that identity, you can issue spending instruments.

Why virtual cards (per agent, per workflow)

  • Per-merchant and per-category controls prevent misuse
  • Spend caps, velocity limits, and time windows reduce risk
  • One card per workflow keeps blast radius small and reconciliation easy
  • Instant revoke/rotate if an integration is compromised

The safety model: policy-first, real-time

Spending must be authorized by policy before it leaves the wallet. That includes:

  • Allowed merchants/categories
  • Max transaction amount and monthly cap
  • Approved time windows and geos
  • Additional human approvals for high-risk transactions

Autonomous doesn’t mean ungoverned

Every charge should emit rich events: who/what/why/when, linked back to the agent and workflow that initiated it. That’s what enables automated reviews, alerts, and chargeback responses.

What you can ship today

  • Create a wallet per agent
  • Issue virtual cards per workflow
