## Basic Usage

The core module provides a convenient wrapper around the [Node HTTP API](docId\:YynXYcqbLmbWflxZoM4C6), for almost all possible API endpoints.&#x20;

:::CodeblockTabs
```javascript
const {LedgerClientFactory} = require('@signumjs/core');

(async () => {
    const ledger = LedgerClientFactory.create({
        nodeHost: 'https://europe.signum.network',
    });

    const account = await ledger.account.getAccount({accountId: '16107620026796983538'});
    console.log('Account', account);
})();
```

```typescript
import {LedgerClientFactory} from '@signumjs/core';

(async () : Promise<void> => {
    const ledger = LedgerClientFactory.create({
        nodeHost: 'https://europe.signum.network',
    });

    const account = await ledger.account.getAccount({accountId: '16107620026796983538'});
    console.log('Account', account);
})();
```

\<script/>

```javascript
(async () => {
    // the 'namespace' of @signum/core is sig$
    const ledger = sig$.LedgerClientFactory.create({
        nodeHost: 'https://europe.signum.network',
    });

    const account = await ledger.account.getAccount({accountId: '16107620026796983538'});
    console.log('Account', account);
