# Native network balances (ie. ETH, MATIC, etc.)

## Fetch native network balance (aka ETH on Ethereum, MATIC on Polygon, AVAX on Avalanche, BNB on BSC, etc.)

*Sequence Indexer `GetEtherBalance` Method:*

* Request: POST /rpc/Indexer/GetEtherBalance
* Content-Type: application/json
* Body (in JSON):
  * `accountAddress` (string) -- the wallet account address

**Example: `GetEtherBalance` MATIC balance of a wallet account address on Polygon using an `API_Access_Key`**
