Massive Gemini API bill in 48 hours

A reported leaked API key led to runaway usage and a devastating spike in charges.

Usage spike detected +455x

Without guardrails Too late

With LocklyAI Blocked early

Modern API apps need better guardrails.

API providers are great at billing usage. They’re not always great at stopping catastrophic misuse before the damage is done.

1 leak is all it takes to expose an expensive API key

48 hours can be enough for a small team to face a devastating bill

1 layer between your app and the provider can change everything

The problem today

✕Leaked API keys can be abused instantly.

✕Most teams notice the damage only after the bill arrives.

✕Small teams rarely have real-time budget protection.

✕One mistake in code, logs, or config can become expensive fast.
