# List unsubscribe groups

> Offset pagination only (`page[number]` default 1, `page[size]`
default 25, max 100). No `sort`/`filter`/cursor — ordering fixed
`desc created_at, desc id`. Uses the shared `QueryParser.parse_offset/1`
— a malformed `page` (e.g. flat `?page=1` instead of
`?page[number]=1`) returns `400` (code `10015`), consistent with
`GET /v2/email_blocks`. `meta` includes `total_pages`.

        and the body `code` carries that same status (e.g. `"406"`, not a
        hardcoded `"500"`). The explicit `500.json` clause still emits
        `code: "500"` for genuine 500s.
