Lists a namespace's values in key order.

- **Path** `GET https://api.data.sylphx.com/v1/kv/namespace-id`
- **Scope** `data:read`
- **Effect** `read` — nothing is written.
- **Collection** [kv](/docs/api/kv)
- **Query** `prefix`, `page_size`, `page_token`
- **Host** `https://api.data.sylphx.com`

## Request

| Field | Type | What it is |
| --- | --- | --- |
| `namespace_id` | `string` | The namespace's id. Required. |
| `prefix` | `string` | Only keys with this prefix. |
| `page_size` | `uint32` | At most this many entries; the service caps it. |
| `page_token` | `string` | The `next_page_token` of the previous page. |

## Response

| Field | Type | What it is |
| --- | --- | --- |
| `values` | `ValueRecord[]` | The page of entries. |
| `next_page_token` | `string` | Empty on the last page. |

### ValueRecord

| Field | Type | What it is |
| --- | --- | --- |
| `namespace_id` | `string` | The namespace's id in the environment, for example `ratelimit`. |
| `key` | `string` | The key. |
| `value` | `bytes` | The bytes, base64. |
| `sha256` | `string` | `sha256:<hex>` of the value. |
| `version` | `uint64` | The version, increasing per key. |
| `expires_at_unix_ms` | `int64` | Expiry in Unix milliseconds; zero never expires. |
| `updated_at_unix_ms` | `int64` | When this version was written, in Unix milliseconds. |

## Errors
