# Authentication

TheSDK uses API keys for authentication. You can obtain your API key from the [Browserable Cloud Dashboard](https://app.browserable.ai) or from your local admin dashboard ([http://localhost:2001/dash/@admin/settings](http://localhost:2001/dash/@admin/settings)).

## Setting Up Authentication

When initializing the SDK, provide your API key in the constructor:

```typescript theme={null}
import { Browserable } from 'browserable-js';

const browserable = new Browserable({
  apiKey: 'your-api-key'
});
```

## Custom Base URL

By default, the SDK uses `https://api.browserable.ai/api/v1` as the base URL. If you need to use a different base URL (for example, in development or testing), you can specify it in the constructor:

```typescript theme={null}
const browserable = new Browserable({
  apiKey: 'your-api-key',
  baseURL: 'https://custom-api.example.com/api/v1'
});
```

## Verifying Authentication

You can verify that your API key is valid by using the `check()` method:

```typescript theme={null}
try {
  const result = await browserable.check();
  if (result.success) {
    console.log('API key is valid!');
  }
} catch (error) {
  console.error('Failed to validate API key:', error);
}
```
