FAQ

Which APIs do you support?
We support OpenAI, Stripe, AWS, and more. You connect via read-only API keys — we never write to your accounts.
How does anomaly detection work?
We build a rolling baseline from your last 30 days of usage. If a period deviates by more than your configured threshold (default 2×), you get an alert.
Can I set my own cost thresholds?
Yes. You can set hard dollar limits per integration or rely on the learned baseline. Both can trigger alerts independently.
