# `getBlocks`

Returns a list of confirmed blocks between two given slots. <CreditCost network="solana" method="getBlocks" />

## Parameters

- `startSlot`: (integer) _[required]_ - The starting slot number for the range of blocks to query.
- `endSlot`: (integer) _[optional]_ - The ending slot number for the range of blocks to query.
  Must be no more than 500,000 blocks higher than `startSlot`.
- `config`: (object) _[optional]_ - Configuration object with the following options:
  - `commitment`: (string) _[optional]_ - The commitment level to use for the query. The default is `finalized`. Possible values are:
    - `finalized` - Queries the most recent block confirmed by a super majority of the cluster as having
      reached maximum lockout, meaning the cluster has recognized this block as finalized.
    - `confirmed` - Queries the most recent block that has been voted on by a super majority of the cluster.

## Returns

`result`: (integer) - An array of `u64` integers representing the block numbers within the specified range. If `endSlot` is not
