The table below shows this endpoint's support for
[blocking queries](/api/index.html#blocking-queries) and
[required ACLs](/api/index.html#acls).
| Blocking Queries | ACL Required |

| `YES` | `namespace:read-job` |
### Parameters
- `prefix` `(string: "")`- Specifies a string to filter evaluations on based on
an index prefix. This is specified as a querystring parameter.
