## Example Request and Response

### Prerequisites

Before making requests with NO.AI SDK, you must have it installed.

You can install NO.AI SDK using either **`npm`** or **`yarn`**. Use the following commands to install NO.AI SDK:

```sh
npm install @nest25/wallet-lib
OR
yarn add @nest25/wallet-lib
```

### Request

Here is an example of how to make a `transfer` request using the NO.AI SDK:

{% code overflow="wrap" %}

```javascript
// import Nest SDK
import { Wallet } from 'nest25/wallet-lib';

// Create a new instance of the Wallet class
const wallet = new Wallet();
// test mnemonic for BTC mainnet (use the createWallet function to get one)
const testMnemonic = 'divorce poverty spend fire symbol market good skull rebel surge giggle album';
// receiver address
const receiver = '0xd040591F093eacFAB8734350aac24703a0081f29';

const main = async () => {
  // transfer 0.1 AVA from the test mnemonic to the receiver address
  const response = await wallet.transfer('sol',testMnemonic,receiver,'0.1');
  // print the response
  console.log(response);
};

main();
```

{% endcode %}

### Response

{% code overflow="wrap" %}

```sh
 {
        code: 1,
        result: '5oWsXKXkTYxWUeBtyhaC6xxx7ZNRXW5qq1PJpbas1y4zQqgD9mxPGBF2zCeUkVHornFDo63hriUdVGuPp49u5Tvy'
