Frequently Asked Questions

How does the size tracking work?

We send HTTP requests to your configured endpoints on a schedule and record the Content-Length or measured byte size of each response, storing it with a timestamp so you can see trends.

What counts as a response size problem?

Any unexpected growth — a payload that doubles over a week, a list endpoint that grows unbounded, or a single response that exceeds your mobile bandwidth budget — can be caught early with threshold alerts.

Do you support authenticated endpoints?

Yes. You can configure custom headers (e.g. Authorization: Bearer ...) per endpoint so we can measure protected API responses just like public ones.
