Know when your AI spend spikes — in minutes, not at month-end

0x24 watches your Anthropic, OpenAI and Gemini usage through their read-only reporting APIs and alerts you the hour something goes wrong: a runaway agent loop, a leaked key, a misconfigured batch job.

Read-only by construction · keys stored encrypted · no agents, no SDKs, no code changes

0x24 is the character code of $ — watching the dollar sign is the whole job.

🚨 anthropic: $42.10 in the bucket starting 14:00 UTC — 9.3x the baseline ($4.52 median of last 120 buckets).

How it works

No SDK, no proxy, no code changes. 0x24 reads the same reporting APIs your provider's billing console uses.

01

Connect a reporting key

Create a dedicated admin key with reporting-only scope in your provider's console and paste it once. It's verified live and stored encrypted.

02

We poll, hourly-grained

Every few minutes 0x24 pulls cost reports (billing truth) and hourly usage (fast signal) and builds your 7-day baseline per provider.

03

You get the alert

Spikes vs baseline and budget thresholds (50/80/100%) land in your dashboard — and in Telegram, within minutes of the anomaly.

Built for teams that ship with LLMs

The invoice at month-end is an autopsy. 0x24 is the smoke detector.

Read-only by construction

Only reporting endpoints, ever. 0x24 can't touch your workloads, keys or billing — the code has no write path to your providers.

Spike detection

Current hour vs your trailing 7-day baseline. New accounts stay silent until a baseline exists — no alert spam on day one.

Budgets that shout early

Daily and monthly budgets with 50/80/100% thresholds, each fired once per period. Powered by provider cost reports — the billing truth.

Encrypted key storage

Provider keys are encrypted at rest and never displayed again — only a 4-character hint. Use reporting-scope keys, revocable any time.

Telegram-fast delivery

Link Telegram in one click and alerts reach your phone in seconds. Dashboard keeps the full history either way.

Multi-provider

Anthropic, OpenAI and Google (Gemini) today; OpenRouter and Bedrock on the roadmap. One baseline, one alert channel, all your LLM spend.

Your next runaway loop is a matter of time
