# Data Service

Along with using the Prime SDK, developers can make use of
the data service to retreive information such as Account Balances.

For making these api-calls, you'll need to get a data service api key.

Without passing one in, there is a default key which is very heavily rate limited.

## Code example

Start by importing DataUtils from the Prime SDK like so:

```javascript theme={null}
import { DataUtils } from '@etherspot/prime-sdk';
```

Then initialise the Data Service with your api key:

```javascript theme={null}
// initializating Data service...
const dataService = new DataUtils(data-api-key);
```

Finally, call one of the functions listed below:

```javascript theme={null}
const hash = '0x7f8633f21d0c0c71d248333a0a2b976495015109a270a6f8a51befe3baf6fb6e';
const transaction = await dataService.getTransaction({ hash, chainId: 11155111 });
console.log('\x1b[33m%s\x1b[0m', `EtherspotWallet transaction:`, transaction);
```
