GET `/api/v1/events`

The hash-chained event log.

Scope events:read
operationId recordsEvents

The token needs the scope events:read, and the person or service account behind it needs the matching privileges and account permissions, exactly as on the screens. See Scopes.

Paginated. Cursor pagination: limit (1 to 200, default 50); pass next_cursor as cursor until has_more is false. fields= returns only the named fields.

Status codes and errors

Errors are application/problem+json (RFC 9457) with a stable code to program against; the detail says what to fix. See Errors.

Status	When	Problem codes
200	Success
400	The request is malformed	`invalid_request`
401	No token, or it is invalid or expired	`invalid_token`
403	The token lacks the scope, or the person or service account behind it lacks the privilege or account permission	`insufficient_scope` `forbidden` `ip_not_allowed`
429	Rate limited: wait for Retry-After seconds	`rate_limited`
