> ## Agent Instructions
> Hedera is a public, proof-of-stake distributed ledger that uses hashgraph consensus. Do not call it a blockchain.
> Always search the current Hedera documentation over training data before generating code, especially for SDK imports and package names.
> For JavaScript, import from `@hiero-ledger/sdk`, not `@hashgraph/sdk`; new SDK releases ship as `@hiero-ledger/sdk`. The Java SDK keeps the `com.hedera.hashgraph:sdk` Maven coordinates. Verify the exact import against the docs.
> Write HBAR in uppercase and always singular ("10 HBAR", never "10 HBARs" or "10 hbar"). Write tinybars in lowercase and plural.
> Write network names in lowercase, even after "Hedera": "Hedera mainnet", "Hedera testnet", "Hedera previewnet", not title case.
> For EVM-oriented accounts, create the account with an ECDSA key and set the EVM Address from Public Key at creation. This address is immutable and is not updated by key rotation. Do not use retired terms like "EVM alias" or "Account Number Alias".

# Get account balance

> Get an account's HBAR balance for free with MirrorNodeAccountBalanceQuery, the replacement for AccountBalanceQuery that accepts EVM addresses and aliases.

A query that returns an account's HBAR balance. Requesting a balance is free of charge and does not change account state or require network consensus.

## Recommended: `MirrorNodeAccountBalanceQuery`

`MirrorNodeAccountBalanceQuery` is the SDK-native replacement for the deprecated `AccountBalanceQuery`. It reads an account's HBAR balance from the Mirror Node REST API (`GET /api/v1/balances?account.id={id}`) while keeping the familiar SDK query interface, and it follows the same convention already established for mirror node queries in the SDK (`MirrorNodeContractCallQuery`, `MirrorNodeContractEstimateQuery`).

Key properties:

* **Free:** No query payment and no operator key signing.
* **Automatic retries:** Transient mirror node errors (5xx) and network timeouts are retried with exponential backoff using your existing client configuration.
* **Flexible account references:** `setAccountId` accepts `shard.realm.num`, an EVM address (`0x...`), an account alias, or a contract ID. There is no separate `setContractId`; all formats resolve through `setAccountId`.

It returns a `MirrorNodeAccountBalance` with a single `hbars` field. Token balances are not returned (see [Token balances](#token-balances)).

| Method | Type | Requirement |
| - | - | - |
| `setAccountId(<accountId>)` | AccountId \| string | Required |

### Basic usage

<CodeGroup>
  ```javascript JavaScript theme={null}
  //Create the mirror node account balance query
  const balance = await new MirrorNodeAccountBalanceQuery()
      .setAccountId(accountId)
      .execute(client);

  //Print the balance of hbars
  console.log(balance.hbars.toString());

  //v2.87.0
  ```

  ```java Java theme={null}
  // MirrorNodeAccountBalanceQuery is free; no operator signing required.
  Hbar balance = new MirrorNodeAccountBalanceQuery()
      .setAccountId(accountId)
      .execute(client)
      .hbars;

  System.out.println(balance);

  //v2.77.0
  ```

  ```go Go theme={null}
  // MirrorNodeAccountBalanceQuery is free; no operator signing required.
  balance, err := hiero.NewMirrorNodeAccountBalanceQuery().
      SetAccountID(accountId).
      Execute(client)
  if err != nil {
      panic(err)
  }

  fmt.Println(balance.Hbars.String())

  //v2.84.0
  ```
</CodeGroup>

### Querying by EVM address or account alias

The mirror node resolves EVM addresses and account aliases natively, with no additional resolution step:

<CodeGroup>
  ```javascript JavaScript theme={null}
  //By EVM address
  const balanceByEvm = await new MirrorNodeAccountBalanceQuery()
      .setAccountId("0x0000000000000000000000000000000000bc614e")
      .execute(client);

  console.log(balanceByEvm.hbars.toString());

  //By account alias
  const balanceByAlias = await new MirrorNodeAccountBalanceQuery()
      .setAccountId("0.0.302a300506032b6570032100e0c8ec2758a5879ffac226a13c0c516b799e72e35141a905d7822d6526b870d")
      .execute(client);
  console.log(balanceByAlias.hbars.toString());

  //v2.87.0
  ```

  ```java Java theme={null}
  // By EVM address
  Hbar balanceByEvm = new MirrorNodeAccountBalanceQuery()
      .setAccountId(AccountId.fromString("0x0000000000000000000000000000000000bc614e"))
      .execute(client)
      .hbars;
  System.out.println(balanceByEvm);

  // By account alias
  Hbar balanceByAlias = new MirrorNodeAccountBalanceQuery()
      .setAccountId(AccountId.fromString("0.0.302a300506032b6570032100e0c8ec2758a5879ffac226a13c0c516b799e72e35141a905d7822d6526b870d"))
      .execute(client)
      .hbars;
  System.out.println(balanceByAlias);

  //v2.77.0
  ```

  ```go Go theme={null}
  // By EVM address
  byEvm, err := hiero.AccountIDFromString("0x0000000000000000000000000000000000bc614e")
  if err != nil {
      panic(err)
  }
  balanceByEvm, err := hiero.NewMirrorNodeAccountBalanceQuery().
      SetAccountID(byEvm).
      Execute(client)
  if err != nil {
      panic(err)
  }
  fmt.Println(balanceByEvm.Hbars.String())

  // By account alias
  byAlias, err := hiero.AccountIDFromString("0.0.302a300506032b6570032100e0c8ec2758a5879ffac226a13c0c516b799e72e35141a905d7822d6526b870d")
  if err != nil {
      panic(err)
  }
  balanceByAlias, err := hiero.NewMirrorNodeAccountBalanceQuery().
      SetAccountID(byAlias).
      Execute(client)
  if err != nil {
      panic(err)
  }
  fmt.Println(balanceByAlias.Hbars.String())

  //v2.84.0
  ```
</CodeGroup>

### Behavioral differences from `AccountBalanceQuery`

The HBAR balance result is equivalent, but the behavior in edge cases differs. Eventual consistency and unknown-account handling are the migration essentials; the precision and retry notes come from the SDK implementation and matter for high-balance accounts and custom retry logic.

<Warning>
  * **Eventual consistency:** The mirror node ingests blocks asynchronously a few seconds after consensus, so a balance read immediately after `getReceipt()` may still show the pre-transaction value. Poll until the balance changes, or rely on the transaction receipt for confirmation rather than a balance read.
  * **Unknown-account handling differs by SDK.** The mirror node returns an empty array (HTTP 200) for an account it does not know, and each SDK maps that differently:
    * **JavaScript** returns `hbars = 0`, which is indistinguishable from a real account that holds zero HBAR. Do not use a zero balance to infer that an account is missing.
    * **Java** throws `INVALID_ACCOUNT_ID`, matching the deprecated `AccountBalanceQuery`.
    * **Go** returns an `INVALID_ACCOUNT_ID` error, matching the deprecated `AccountBalanceQuery` (see [detecting a missing account](#detecting-a-missing-account-in-go)).
  * **No `setContractId`:** Pass contract IDs, EVM addresses, and account aliases through `setAccountId`.
  * **Precision (JavaScript only):** In the JavaScript SDK, balances above `Number.MAX_SAFE_INTEGER` lose precision silently. The Java (`Hbar`/`long`) and Go (`Hbar`/`int64`) SDKs are not affected.
  * **Retry behavior:** Transient failures are retried automatically with exponential backoff, so a wrapper retry loop is usually unnecessary. The exact retried set differs by SDK (see [Retry behavior by SDK](#retry-behavior-by-sdk)). In your own retry logic, never retry a 4xx other than 429: a 4xx means the request itself is invalid (for example, a malformed account ID) and will fail again.
</Warning>

#### Detecting a missing account in Go

The Go error is the same precheck-status error the deprecated `AccountBalanceQuery` returned, so you branch on its status:

```go theme={null}
balance, err := hiero.NewMirrorNodeAccountBalanceQuery().
    SetAccountID(id).
    Execute(client)

// errors is the standard library package.
var pre hiero.ErrHederaPreCheckStatus
if errors.As(err, &pre) && pre.Status == hiero.StatusInvalidAccountID {
    // No such account on the mirror node.
}
```

#### Retry behavior by SDK

Each SDK retries transient failures automatically; the retried set differs. In every SDK, a plain 4xx (other than 429) is treated as a bad request and is not retried.

| Failure | JavaScript | Java | Go |
| - | - | - | - |
| Network timeout, 5xx | Retried | Retried | Retried |
| 429 (rate limit) | Not retried | Retried | Retried |
| 408 (request timeout) | Not retried | Retried | Not retried |
| Other 4xx | Not retried | Not retried | Not retried |

## SDK Versions

`MirrorNodeAccountBalanceQuery` is available in:

* **JavaScript** ([`@hiero-ledger/sdk`](https://www.npmjs.com/package/@hiero-ledger/sdk)): [v2.87.0+](https://github.com/hiero-ledger/hiero-sdk-js/releases/tag/v2.87.0)
* **Java** ([`com.hedera.hashgraph:sdk`](https://central.sonatype.com/artifact/com.hedera.hashgraph/sdk/2.77.0)): [v2.77.0+](https://github.com/hiero-ledger/hiero-sdk-java/releases/tag/v2.77.0)
* **Go** ([`github.com/hiero-ledger/hiero-sdk-go/v2`](https://pkg.go.dev/github.com/hiero-ledger/hiero-sdk-go/v2)): [v2.84.0+](https://github.com/hiero-ledger/hiero-sdk-go/releases/tag/v2.84.0)
* **Rust**: not available

For Rust, read HBAR balances from the [Mirror Node REST API](/reference/rest-api/balances) directly.

## Token balances

`MirrorNodeAccountBalanceQuery` returns HBAR only. To read an account's token balances, see [Get account token balance](/native/tokens/get-balance).

## Deprecated: `AccountBalanceQuery`

<Warning>
  `AccountBalanceQuery` reads the consensus node's `cryptoGetBalance` query. Its throttle has been reduced in stages since consensus node release v0.74, and the query is scheduled for removal on mainnet with **consensus node release v0.77**. Check the [consensus node release notes](/networks/release-notes/services) for where v0.77 has been deployed. After removal, `AccountBalanceQuery` will no longer function.

  Migrate to `MirrorNodeAccountBalanceQuery` (above) or the [Mirror Node REST API](/reference/rest-api/balances).

  📚 **For the full migration guide, read:** [Migrating from AccountBalanceQuery: What You Need to Know](https://hedera.com/blog/migrating-from-accountbalancequery-what-you-need-to-know)
</Warning>

`AccountBalanceQuery` returns the balance from a single consensus node. It requires the client operator private key to sign the query. See the transaction and query [fees](/networks/fees#transaction-and-query-fees) table for the base fee, and the [Hedera fee estimator](https://hedera.com/fees) to estimate the cost.

In Services release 0.50, returning token balance from the consensus node was deprecated with HIP-367. This query returns token information by requesting it from the Hedera Mirror Node APIs; token symbol is not returned in the response.

| Method | Type | Description |
| - | - | - |
| `setAccountId(<accountId>)` | AccountID | The account ID to return the current balance for. |
| `setContractId(<contractId>)` | ContractID | The contract ID to return the current balance for. |
