Frequently Asked Questions

How does per-user cost tracking work?

You instrument your app with our JavaScript SDK or send events via webhook. Each API call is tagged with a user ID, and we aggregate costs in real time on your dashboard.

Which AI providers are supported?

OpenAI, Anthropic, Cohere, Mistral, and any provider with a token-based pricing model. Custom pricing tables are supported too.

What happens when a user exceeds my threshold?

You receive an instant alert via email and/or webhook. You can then rate-limit, upsell, or block that user — the action is always yours to take.
