### `at.happyproto.registry.listVersions`

**Type**: `query`

#### Parameters

| `did` | `string` (did) | Yes | The publisher. |
| `limit` | `integer` | No |  |
| `name` | `string` | Yes | The project's name, which is the record key of its software.release.project: 1 to 64 lowercase letters, digits and interior hyphens. |

#### Output

**Encoding**: `application/json`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `cursor` | `string` | No | Absent on the last page. |
| `versions` | `array` | Yes |  |

#### Errors
