Reads up to 1000 keys at once (MGET). Answers one entry per key, in order; an absent or expired key keeps its key and has no `value`.

- **Path** `POST https://api.data.sylphx.com/v1/kv-mget`
- **Scope** `data:read`
- **Effect** `read` — nothing is written.
- **Collection** [kv](/docs/api/kv)
- **Host** `https://api.data.sylphx.com`

## Response

| Field | Type | What it is |
| --- | --- | --- |
| `values` | `ValueRecord[]` | One entry per key, in the order asked; an absent or expired key keeps its key and has no `value` or `version`. |

### ValueRecord

| Field | Type | What it is |

| `value` | `bytes` | The bytes, base64. |
| `sha256` | `string` | `sha256:<hex>` of the value. |
| `version` | `uint64` | The version, increasing per key. |
