Method	`GET`
Operation	`ListLLMAnnotations`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Lists human annotations on traces and observations, optionally scoped to one review queue.

Callers need the viewer role; the runtime's own gate enforces it.

Request

5 fields.

Field	In	Type	Required	Description
`traceId`	query	string	—	TraceID narrows to annotations on one trace.
`queue`	query	string	—	Queue narrows to one review queue.
`status`	query	string	—	Status narrows to one review status, e.g. PENDING.
`offset`	query	integer	—	Offset is how many rows to skip, for paging.
`limit`	query	integer	—	Limit caps how many rows come back.

Response

Status	Body	Meaning
