# Provider
This feature is available in the [Hedera JavaScript SDK](https://github.com/hashgraph/hedera-sdk-js) only. (version >=2.14.0).
`Provider` provides access to a Hedera network to which requests should be submitted to. The Hedera network can be specified to `previewnet`, `testnet`, or `mainnet`.
The most important method on the provider interface is the `call` method which allows a user to submit *any* request and get the correct response for that request. For instance,Java
```javascript theme={null}
// Balance of node account ID 0.0.3
const balance = provider.call(new AccountBalanceQuery().setAccountId(AccountId.fromString("0.0.3")));Interface Provider
```
