The circuit breaker for your token spend.
One runaway agent loop can burn a month's API budget overnight. TokenGuard sits in front of your LLM calls, tracks spend in real time, and hard-stops the moment a loop crosses your limit — before the bill, not after.
Three steps between your agent and a $4,000 mistake
Point your calls at TokenGuard
Swap one base URL. Every request to your LLM provider now passes through the proxy first — no SDK changes, no rewrite.
It meters spend in real time
Every prompt and completion is counted and priced as it happens, against a per-run and per-day budget you set — not reconciled hours later on an invoice.
It trips before you overspend
Cross the limit and the next call is refused, not logged-and-forwarded. A runaway loop stops at your number instead of at your credit-card ceiling.
Put a hard limit on your agent's spend.
TokenGuard is in early access. Leave your email and we'll reach out when self-serve proxy keys open up.
