# debug_accountRange | Robinhood

> Robinhood Chain API method that enumerates all accounts at a given block with paging capability. debug_accountRange on Robinhood Chain via Chainstack.

Robinhood Chain API method that enumerates all accounts at a given block with paging capability. This method returns a range of accounts stored in the state trie, providing account details such as balance, nonce, code hash, and storage. It is useful for state inspection and debugging purposes.

<Note>
  Learn how to [deploy a node](/docs/debug-and-trace-apis#robinhood) with the debug and trace API methods enabled.
</Note>

<Warning>
  This method is available for post-Nitro blocks only (block 22,207,815 and later). For pre-Nitro blocks, use the `arbtrace_*` methods instead.
</Warning>

## Parameters

* `blockNrOrHash` — the block number in hex format or block tag (`latest`, `earliest`, `pending`, `safe`, `finalized`), or block hash.
* `start` — the start key hash for pagination, encoded as hex bytes. Use `0x0000000000000000000000000000000000000000000000000000000000000000` to start from the beginning.
* `maxResults` — the maximum number of accounts to return. Capped at 256.
* `nocode` — if `true`, excludes contract bytecode from the result.
* `nostorage` — if `true`, excludes storage data from the result.
* `incompletes` — if `true`, includes accounts without known addresses.

## Response

* `result` — an object containing the state dump:
  * `root` — the state root hash of the block.
  * `accounts` — a map of account addresses to account data:
    * `balance` — the account balance in Wei.
    * `nonce` — the account nonce.
    * `root` — the storage root hash.
    * `codeHash` — the hash of the account's contract code.
    * `code` — the contract bytecode (omitted if `nocode` is `true`).
    * `storage` — the account's storage slots (omitted if `nostorage` is `true`).
    * `address` — the account address.
  * `next` — the next key hash for pagination. Use this value as the `start` parameter in the next call to continue iterating.
