Trust middleware
for AI agents
The runtime safety layer that stops agent loops, blocks attacks, and slashes your API bill — all in one line of code.
Nine layers.
One proxy.
Circuit Breaker
Stops runaway agent loops before they burn your budget.
Deduplication
Catches duplicate actions — even when rephrased. Never charge a customer twice.
Prompt Firewall
Blocks injection attacks, internal URLs, and secret leaks before they reach your model.
Cost Policies
Set per-agent budgets. Get alerts before things spiral out of control.
Audit Trail
Every tool call, every decision — logged and searchable. Compliance-ready.
Retry Intelligence
Smart backoff that cuts failure costs by 90% instead of hammering the same error.
Side-effect Safety
Guarantees payments process once. Emails send once. No double-writes. Ever.
Model Routing
Auto-failover between models when quality degrades or costs spike.
Silence Detection
Heartbeat monitoring. No more agents going dark without anyone noticing.
BY THE NUMBERS
