THE PROBLEM

Alerts tell you the fire started. Hard controls keep it small.

Developers repeatedly report missing spend ceilings, browser-exposed keys and service-account abuse. Native controls are improving, but they differ by provider and can still leave gaps.

FREE LOCAL DIAGNOSTIC

Find the weakest link in your API bill controls.

Paste only code or configuration you are allowed to inspect. Analysis happens locally in this tab; nothing is transmitted.

  • No upload and no analytics tracker
  • Known secret prefixes are masked in the report
  • Exportable remediation plan

This is a security checklist, not a guarantee or provider-side kill switch.

CONTAINMENT, NOT PANIC

Rotate. Restrict. Cap. Revoke. Prove.

A useful response is ordered: stop exposure, remove old credentials, enforce provider restrictions, test the ceiling, then preserve an audit trail.

BUDGET BUFFER

Know how close you are to the line.

Model a conservative emergency buffer. This does not replace provider billing data, but it makes an alert-only setup visible.

PUBLIC EVIDENCE

Built from real losses, requests and counterevidence.

We do not claim every provider lacks controls. Google introduced spend caps and tightened unrestricted keys; self-hosted alternatives exist. The gap is consistent, low-ops protection across providers.

HONEST LIMITS

This scanner cannot shut down your provider account.

01

Static, local analysis

It detects risky patterns and configuration gaps, not live account activity.

02

Rotate exposed secrets

Masking a key in code is not enough. Revoke it at the provider.

03

Test native controls

Provider limits, delays and account behavior change. Verify them directly.

Make the next invoice boring.
