Frequently Asked Questions

How does API cost tracking work?

Send your API logs via webhook or our lightweight SDK. We process each request in real-time, calculate cost based on your pricing model, and attribute it to the correct customer.

Which API platforms are supported?

Any HTTP-based API. We support custom webhooks, so you can integrate with REST, GraphQL, or gRPC services regardless of your stack.

Can I set alerts for expensive customers?

Yes. Configure spend thresholds per customer or endpoint and receive instant email or Slack notifications when limits are exceeded.
