# Quick Setup with JavaScript Client Library

Setting up the JavaScript Client Library for VYSP API is easy. Follow these steps to integrate it into your project.

## Installation

Use npm to install the library:

## Basic Usage

Here is a simple example to get you started:

```javascript

const client = new VYSPClient({
    tenantApiKey: 'your_tenant_key',
    gateApiKey: 'your_gate_key'
});

const prompt = 'sample input';
const modelOutput = 'sample model output';

async function performCheckInput() {
    try {
        const response = await client.checkInput('user1', prompt);
        console.log(response);
    } catch (error) {
        console.error('Error:', error.message);
    }
}

async function performCheckOutput() {
    try {
        const response = await client.checkOutput('user1', prompt, modelOutput);
        console.log(response);
    } catch (error) {
