HOW IT WORKS

Built for how agents actually spend

Issue just-in-time single or multi-use funded virtual cards to AI agents, letting them complete purchases autonomously under rules you define.

01

Set policies

Register your agent and define spend limits, allowed merchants, categories, and velocity controls.

02

Intent declaration

Before any purchase, agent declares what it wants to buy, where, and for how much.

03

Card issuance

If intent passes your policies, a virtual card is auto-created and locked to the declared intent.

04

Checkout

Agent retrieves card credentials (PAN, CVV, expiry) and completes the purchase at checkout.

05

Auto audit

Every transaction is automatically verified against the declared intent. Mismatches are flagged.

FEATURES

Every guardrail you need, none of the friction.

01

Flexible Card Types

Single-use cards auto-close after one charge. Multi-use cards support velocity limits, TTL, active hours, and merchant locks. Issue in under 50ms via API.

02

Custom Spend Policies

Define per-agent policies with spend limits, merchant restrictions, and approval workflows. Require intent declaration before card access. Auto-freeze on policy violations.

03

Real-time Tracking

Stream every event via webhooks: authorizations, settlements, anomalies. Full audit trail with intent correlation. Export compliance reports on demand.

04

Dispute Management

Handle chargebacks and disputes with full transaction evidence. Intent attestations provide proof of authorized purchases. Automated dispute response workflows.
