Every agent transaction. Checked in milliseconds.
Three steps to autonomous spend governance.
Point your agents at Reins. One API call to start tracking every transaction.
Define spend caps, vendor blocks, and approval flows. Per agent or fleet-wide.
Every transaction is checked in milliseconds. Block, flag, or approve automatically.
Monitor every transaction as it happens. See which agents are spending, where their money goes, and enforce policies automatically.
Your AI agents are making hundreds of micro-transactions per day. Calling paid APIs, provisioning compute, purchasing data feeds. Each one is a financial decision made without human oversight. The payment rails exist. The governance doesn't.
You can't see what your agents are spending, where, or why. Costs appear as a single line item on your cloud bill.
One misconfigured agent can burn through your entire API budget in hours. No spend limits, no approved vendor lists, no alerts.
Auditors will ask what your agents bought and why. Today you have no answer. Tomorrow regulators will too.
Real-time monitoring, automated policy enforcement, and intelligent cost optimization.
See every agent transaction as it happens. Filter by agent, vendor, API, cost. Know exactly where your money goes.
Set spend limits per agent, approve vendor lists, block categories. Policies enforce automatically, no human in the loop.
ML-powered alerts when an agent's spending pattern deviates. Catch runaway costs before they hit your bill.
Automatically identify cheaper API alternatives, consolidate vendor spend, and surface savings opportunities.
Every transaction logged with full context: which agent, what task, what outcome. Compliance-ready from day one.
Integrates with any agent framework and payment provider. Drop-in governance for your existing stack.
