## 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 `availableContracts` request using the NO.AI SDK:

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

const info = new BlockchainInfo();

async function main() {
    const response = await info.availableContracts('klay')
    console.log(response)
}

main();

```

```jsx
```

### Response

```sh
{
        code: 1,
        types: [
          { contract: 'ERC20', parameters: [Object] },
          { contract: 'ERC721', parameters: [Object] },
          { contract: 'ERC1155', parameters: [Object] },
          { contract: 'Soulbound', parameters: [Object] }
        ]
      }
```

## Use Cases

* The `listAvailableContracts` function can be used to fetch a list of available contracts for a specific blockchain supported by the blockchain gateway. It can be helpful when providing a selection of contract types for users to choose from or when validating the contract type input in other functions.
