AI Agent Spend Guardrails · Done-For-You

Agent spend guardrails,
installed in 48 hours.
You pay when the test passes.

Not a dashboard. Not a report. We wire hard spend controls directly into your agent stack — spawn budgets, kill switches, real-time metering — prove they trigger with a controlled test, and hand you the keys. Fixed €5,000. One engineer-hour of your time.

Why ScaleToZero

Other tools point.
We fix.

Every other FinOps product gives you recommendations and expects your engineers to act on them. They never do. ScaleToZero is different: we implement the enforcement directly in your stack — spawn budgets, kill switches, metering — prove it works with a witnessed acceptance test, and hand you the keys. Done for you, in 48 hours, for one fixed fee.

How it works

Four steps from kickoff
to proven.

01

Scoping Call

15 minutes with your engineering lead. We map your agent stack — frameworks, model providers, the layer where we can meter and enforce. If we can't meter and terminate there, we tell you on the call and you owe nothing.

02

We Implement

48 hours. We wire spawn budgets, spend caps with auto-kill, real-time metering at your layer, the audit sink, and Slack alerting directly into your stack. Your engineer answers questions; we do the work.

03

Acceptance Test, Witnessed

We run a controlled spend burst while you watch. The run must terminate on budget breach, the alert must reach your channel within 60 seconds, and the audit log must reconstruct the full sequence. You sign the result.

04

You Pay, We Hand Over

Your signature on the test triggers the €5,000 invoice — not before. We revoke our access, hand you the keys and the rollback procedure. If any check failed, you owe nothing and we remove everything.

What gets enforced

Five guardrails.
Every run covered.

GUARDRAIL 01

Spawn Budget

A hard ceiling on child-agent fan-out per run, enforced in infrastructure. One prompt can never become 826 agents again.

Kills the runaway at the source
GUARDRAIL 02

Spend Cap + Auto-Kill

A per-run budget that terminates execution the moment it is breached. Not a Slack message for tomorrow — terminated, now.

No human in the loop to miss it
GUARDRAIL 03

Real-Time Metering

Spend measured at the proxy, gateway, or wrapper you control — reconciled against vendor invoices continuously. Your meter stops being a guess.

Your layer, your numbers
GUARDRAIL 04

Immutable Audit Trail

Agent logs written to a sink the agent cannot reach or delete. When something burns, you reconstruct exactly what happened.

Evidence survives the incident
GUARDRAIL 05

Human Alerting

Budget thresholds wired to your Slack or PagerDuty, verified live during the acceptance test. The alert is the receipt, not the protection.

Verified before we leave
STACKS

Where It Runs

LiteLLM, Portkey, OpenRouter proxies; LangChain, CrewAI, OpenAI Agents SDK wrappers; AWS Bedrock / SageMaker with CloudWatch enforcement.

Security & Trust

We thought about safety
before you had to ask.

Scoped Access, Revoked at Handoff

Write access is limited to the guardrail components, granted for the 48-hour window only, and revoked when we hand you the keys. Your team reviews the exact scopes on the kickoff call.

You Sign the Test, Not the Invoice

You approve nothing until the witnessed acceptance test passes. Watch the controlled spend burst, verify the termination, the alert timing, and the audit trail — then sign. Your signature is what triggers the invoice.

24-Hour Undo

All reversible actions can be undone within 24 hours directly from Slack. No support ticket, no delay, no questions.

Production Always Protected

Production-tagged resources are never auto-executed. They always require explicit manual approval on every tier.

Temporary Credentials

Credentials expire after 1 hour. No persistent tokens, no stored keys. We assume role, act, and release every time.

Full Audit Trail

Every scan, action, and approval is logged with timestamp and actor. A complete record of everything we've done.

Fixed fee. Proven before you pay.
