```python
import guava, os

client = guava.Client(
    api_key=os.environ["GUAVA_API_KEY"],   # or omit — reads env automatically
)
```

```typescript
import * as guava from "@guava-ai/guava-sdk";

const client = new guava.Client(
  process.env.GUAVA_API_KEY,  // or omit — reads env automatically
);
```

## Client

`guava.Client` complements [`guava.Agent`](./agent) by providing functions for managing account-level resources. It also provides any functions that don't fit onto [`guava.Agent`](./agent).
