# sui\_getCheckpoints{deprecated} - Sui

This method returns a paginated list of checkpoints on the SUI network. Checkpoints are certified snapshots of blockchain state and are fundamental to SUI's consensus mechanism. This method allows efficient traversal of checkpoint history.

{% hint style="warning" %}
This method is deprecated
{% endhint %}

## Parameters

| Parameter         | Type                | Required | Description                        |
| ----------------- | ------------------- | -------- | ---------------------------------- |
| cursor            | BigInt\_for\_uint64 | No       | Paging cursor (sequence number)    |
| limit             | uint                | No       | Maximum items per page             |
| descending\_order | boolean             | Yes      | Sort order (true for newest first) |

{% hint style="info" %}
The `descending_order` parameter is required and controls whether results are returned with newest checkpoints first (`true`) or oldest first (`false`).
{% endhint %}

## Returns

| Field       | Type    | Description                 |
| ----------- | ------- | --------------------------- |
| data        | array   | Array of checkpoint objects |
| nextCursor  | string  | Cursor for next page        |
| hasNextPage | boolean | Whether more results exist  |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.getblock.io/api-reference/sui-sui/deprecated-json-rpc-methods/sui_getcheckpoints-deprecated-sui.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
