Agent Cards for AI Workflows
Proxy cards let you isolate spend per agent or workflow, enforce strict controls, and keep every payment tied to an auditable intent trail.
Card Types
Dedicated by workflow
Issue a card per agent, task, or team so failures are contained and spend ownership is clear.
Hard controls
Set hard amount caps, merchant restrictions, MCC rules, and velocity limits before transactions are attempted.
Safer credential lifecycle
Keep cards locked by default and reveal sensitive credentials only when intent and policy checks pass.
Verification-ready records
Link card actions and transactions to intent, approval, and policy outcome for operations and compliance.
Policy Controls
Create intent, evaluate policy, issue card access, and verify outcomes with complete evidence logs.
Amount limits
Set strict per-transaction, daily, or monthly limits so agent spend stays inside explicit boundaries.
Merchant controls
Allow or block specific merchants so cards cannot drift into unknown destinations.
MCC restrictions
Block risky categories at authorization time and reduce misuse paths before spend lands.
Velocity caps
Limit transaction frequency to prevent retry loops and runaway autonomous behavior.
Approval thresholds
Auto-approve low-risk spend and route high-risk intent to human review.
Evidence logs
Persist intent, approval, card, and transaction links so every charge can be explained quickly.
Card Setup
Start with intent and policy, then reveal credentials only when the transaction is approved.
