### Buying an Asset

To buy an asset instantly, use the `buy` function from the `buyNow` module:

```typescript
export const buy = async (
        amount: string, 
        signature: Signature, 
        options?: ClientOptions
    )
```

```typescript
const result = await buy(amount, signature, options?);
```

Refer to the Buy Now Module documentation for more details on the `buy` function.
