Frequently Asked Questions
What counts as schema drift?
Any change to the structure of an API response — added or removed fields, changed data types, renamed keys, or altered nesting — is flagged as drift so you can review it before it causes issues.
How does monitoring work?
You register your API endpoints and set a polling interval. The service fetches each endpoint on schedule, extracts the response schema, and compares it against the stored baseline. Deviations trigger an alert immediately.
Can I monitor authenticated APIs?
Yes. You can configure custom request headers — including Authorization tokens and API keys — so the monitor can access protected endpoints just like your own services do.
