FAQ

Is this just a JSON diff tool?
No. APIDiffGuard monitors live endpoints, stores versioned baselines, schedules checks, and alerts on schema drift — the diff viewer is the signature surface, not the whole product.
Can I ignore volatile fields?
Yes. Ignore timestamps, UUIDs, request IDs, etags, and any custom JSON path per endpoint.
Does the CLI use the same engine?
Yes. apidiff check runs the same comparison logic and can fail CI on breaking severity.
What auth types are supported?
Bearer, API key, Basic, OAuth token, and custom headers.
