# eth_getProof | Base

Base API method `eth_getProof` retrieves the account and storage values of the specified account, including the Merkle-proof. This method is used to verify the data without needing the entire state on the client side.

<Note>
  When called against a block older than the latest \~128 blocks, this method is treated as an archive request (2 RUs instead of 1 RU). See [request units](/docs/request-units#archive-state-methods).

## Parameters

* `address` — the address of the account.
* `storageKeys` — an array of storage keys to prove.
* `block` — the block number (in hexadecimal) or one of the strings `"earliest"`, `"latest"`, or `"pending"`, indicating the state to consider. The default is `"latest"`.

## Response

* `result` — an object containing the account proof, balance, code hash, nonce, storage hash, and storage proof for each requested storage key.

## Use case

The `eth_getProof` method is essential for:

* Applications that need to verify account or contract state without syncing the entire blockchain.
* Services that provide cryptographic proofs of specific data to third parties.
* Tools that audit the state of accounts or contracts at specific block heights.
