Frequently asked questions
How does this work?
We sit between your app and the AI API. Every request goes through us, we track the cost in real-time, and enforce your spending limit.
Do I need to change my code?
No code changes needed. Just update your API endpoint to point to us, and we handle the rest.
What happens when I hit my limit?
We immediately stop forwarding requests to the AI provider. Your app gets a clear error response, and you get notified by email.
Which APIs do you support?
OpenAI (GPT-4, GPT-3.5), Anthropic (Claude), Groq, and more. We're adding new providers regularly.
