# debug\_accountRange - Ethereum

Example code for the debug\_accountRange JSON RPC method. Сomplete guide on how to use debug\_accountRange JSON RPC in GetBlock Web3 documentation.

This method returns a range of accounts from the state trie at a specific block, starting from a given key prefix. Used by state-inspection tools and archival analytics to enumerate the account universe at a historical block. Typically requires archive-node access (Dedicated Node tier on GetBlock).
