    }'

    ```json theme={"system"}
    {
      "jsonrpc": "2.0",
      "result": {
        "full": 369624,
        "incremental": 369623
      },

</div>

#### Result Details

When the node has a snapshot, this returns a JSON object with:

* `full: <u64>`
  * Represents the highest full snapshot slot
  * A full snapshot contains the complete state of the blockchain at a specific slot

* `incremental: <u64|null>`
  * Highest incremental snapshot slot based on the full snapshot
  * May be `null` if no incremental snapshot is available
  * Incremental snapshots only record changes since the last full snapshot
