Agent spending control
Agent spending
you don’t have to babysit.
Set the budget once and let your agents spend. Reins gives them a ledger they can never overspend and weighs the intent behind every purchase — hard caps, an approval layer on every charge, and a live, auditable view of every dollar. You hold the reins.

Control without chaos
Speed without risk.
Approval that reads intent.
Every purchase is judged on why, not just how much. The Agentic Advisor weighs what each agent is buying — and the reason it gave — against your policy, then accepts or rejects and records its reasoning. Tune the posture from strict to permissive anytime.

Cards with the rules built in.
Issue Stripe cards scoped to each agent, with merchant categories and safety rules baked into the card itself. Spend is locked to the budget and the controls you set — agents can only transact where you allow.
One place to govern it all.
Set per-item price caps and hourly, daily, and monthly velocity limits, watch budget and cards update live, and audit every transaction and decision — finance and engineering on the same page.
