Agent Cards
Virtual Visa cards for every AI agent

Issue a unique virtual card to each AI agent in your stack. Cards are provisioned instantly via API, tied to a specific agent identity, and work anywhere Visa is accepted.

  • Instant card provisioning
  • Per-agent spend isolation
  • Real-time transaction data
  • Auto-expire on agent retirement
Policy Engine
Spending rules enforced at the network level

Define spend limits in code. Set daily caps, per-merchant restrictions, category blocks, and approval thresholds — enforced at the network level on every authorization, in real time.

  • spend_limit_usd controls
  • MCC category blocks
  • Daily / monthly caps
  • Programmatic rule updates
Approval Inbox
Human-in-the-loop for high-stakes spend

Set approval thresholds so any charge above your limit routes to a human reviewer before it clears. Works over email, Slack, or your own webhook endpoint.

  • Configurable thresholds
  • Slack & email alerts
  • Webhook callbacks
  • Audit trail for every decision
Audit Log
Full transaction history, searchable and exportable

Every authorization, every policy evaluation, every approval decision — logged with full context. Filter by agent, date, merchant, or outcome. Export to CSV or stream to your SIEM.

  • Immutable event log
  • Full-text search
  • CSV & JSON export
  • Webhook streaming
