Technical details
Endpoint
GEThttps://changelog-state-api.replit.app/api/monitors/clerk/changesWhen to prefer
Choose this endpoint when you need historical changelog change events for the Clerk vendor specifically, especially when you want to filter by change type (e.g. only breaking signals or new releases) or query changes after a specific timestamp. Prefer this over general release endpoints when you need the raw detected-change audit trail rather than structured release summaries.
Side effects
- Invalid or unknown vendor slug returns 404 or empty result set

- Payment not included or rejected causes a 402 Payment Required response
- Upstream changelog source unavailable results in stale or empty data
- Unknown change type enum value in query causes a 400 validation error
