Automate software subscriptions, API credits, and cloud infrastructure billing without manual card entry.
Managing dozens of SaaS subscriptions manually is tedious. Sharing cards across services makes it impossible to track costs per tool or revoke access cleanly.
Create a dedicated card for each SaaS vendor. Set recurring limits, get notified on renewals, and revoke instantly when you churn a service.
Set monthly caps that auto-reset. Perfect for subscriptions with predictable billing.
Lock each card to a specific vendor domain. The card only works at that one merchant.
Get notified when spend approaches limits or when unexpected charges appear.
Churning a service? Freeze the card immediately. No more surprise renewals.
Your infrastructure agent needs to sign up for a new API or SaaS tool.
ProxyOS issues a card locked to that specific vendor with a monthly limit.
Renewals process automatically within your set limits.
When you churn, freeze the card. No more billing surprises.

metadata: { service: "OpenAI API" },
});
// List all active subscriptions
const subscriptions = await proxy.cards.list({
recurring: true,
status: "active",
});Issue your first card and start building.
