## Example Request and Response

### Prerequisites&#x20;

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:

```jsx
npm install @nest25/evm-chains-lib
OR
yarn add @nest25/evm-chains-lib
```

### Request

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

```jsx
const { BlockchainInfo } = require('@nest25/evm-chains-lib');

const info = new BlockchainInfo();

async function main() {
    const response = await info.availableBlockchains()
    console.log(response)
}

main();

```
