FAQ
How does billing work?
You pay per token based on the model used. Add credits to your account and they're consumed as you make API requests. When your balance runs low, just top up from the dashboard.
How do your prices compare to going direct?
We add a small 5% margin to provider costs — and unlike other routing services, there are no upfront fees or credit purchase surcharges. You pay per token for exactly what you use. Plus, intelligent routing typically saves 50–85% by picking the optimal model for each request.
What do I get for free?
Free accounts get 60 requests per minute and a $0.50/day spending cap. Enough for development, testing, and prototyping.
What happens if I run out of credits?
You fall back to free tier limits (60 RPM, $0.50/day cap). Add more credits anytime from the billing dashboard.
Are there any rate limits for paid users?
No. Any positive credit balance gives you unlimited requests per minute. We make money when you use the API, so we have no reason to throttle you.
