TokenGuard is a drop-in proxy that sits between your app and the LLM API (Anthropic, OpenAI, and friends). It tracks every token in real time and hard-stops the next request the moment your budget threshold hits — before a misconfigured retry or a stuck agent loop turns into a bill you didn't see coming.
No card required. Validation build — see how it works below.
See token and dollar spend per project, per agent, as it happens — not on next month's invoice.
Set a spending ceiling and TokenGuard blocks the next request the instant you hit it — automatically, before the bill happens, not after.
Point your existing SDK at TokenGuard's proxy URL instead of the provider's. Same code, same calls — budget enforced underneath.
Point your API calls at TokenGuard instead of the provider directly.
Set your budget limits per project or agent.
Get alerted or auto-blocked before you blow your budget.
Drop your email in to register interest for early access — no spam, no bill. This is a pre-launch signup; TokenGuard isn't live yet.
