How TokenGuard Works

1

Replace your API key

Copy-paste our proxy key into your .env. No code changes needed.

from openai import OpenAI

client = OpenAI(
    api_key="tg-proj_...",
    base_url="https://proxy.usetokenguard.com/v1"
)
2

Set your budget

Daily or monthly limits. Hard or soft. You're in control.

3

We enforce it

Requests over budget? Automatically rejected. Or just alerted—your choice.

Frequently Asked Questions

TokenGuard sits between your app and OpenAI. When you make an API call, we check your budget first. If you're under budget, we forward the request. If you're over, we block it (or just alert you—your choice). Every request is logged for real-time visibility.
No. We add <10ms of latency using Cloudflare's edge network. Your users won't notice.
Not yet, but it's coming soon. We're starting with OpenAI, then expanding to Anthropic, Mistral, and more.
You choose. Hard limit = requests are rejected (429 error). Soft limit = requests go through, but you get an alert. You can change this anytime.
Free during beta. After launch: $49/month for Pro (unlimited projects and tracking). Free tier available with limits.
Yes. We encrypt your OpenAI API keys before storage. We never see your prompt data—it's just passed through. We only log metadata (tokens, cost, timestamp).
