*To use the Jovay API, you need an Alchemy account. [Create a free account](https://dashboard.alchemy.com/signup) to get started.*

## What is Jovay?

Jovay is a high-performance Ethereum Layer 2 blockchain built by Ant Digital Technologies, designed for real-world asset (RWA) tokenization. It uses a dual-prover architecture combining Trusted Execution Environments (TEE) and Zero-Knowledge Proofs (ZKP) for cross-verified security, achieving sub-second response times and throughput of up to 22,000 TPS.

## What is the Jovay API?

The Jovay API lets you interact with the Jovay network through a set of JSON-RPC methods. If you've worked with Ethereum's JSON-RPC APIs, the interface will be familiar.

## Get started

### 1. Choose a package manager (npm or yarn)

Pick a package manager for your project's dependencies.

<CodeGroup>
  ```shell npm
  # Begin with npm by following the npm documentation
  # https://docs.npmjs.com/downloading-and-installing-node-js-and-npm
  ```

  ```shell yarn
  # For yarn, refer to yarn's installation guide
  # https://classic.yarnpkg.com/lang/en/docs/install
  ```
</CodeGroup>

### 2. Set up your project

Run the following commands to create and initialize your project:

<CodeGroup>
  ```shell npm
  mkdir jovay-api-quickstart
  cd jovay-api-quickstart
  npm init --yes
  ```

  ```shell yarn
  mkdir jovay-api-quickstart
  cd jovay-api-quickstart
  yarn init --yes
  ```
</CodeGroup>

This creates a new directory named `jovay-api-quickstart` and initializes a Node.js project within it.

### 3. Make your first request

Install Axios to make API requests:

<CodeGroup>
  ```shell npm
  npm install axios
  ```

  ```shell yarn
  yarn add axios
  ```
</CodeGroup>

Create an `index.js` file in your project directory and paste the following code:

<CodeGroup>
  ```javascript index.js
  const axios = require('axios');

  const url = 'https://jovay-mainnet.g.alchemy.com/v2/${your-api-key}';

  const payload = {
    jsonrpc: '2.0',
    id: 1,
    method: 'eth_blockNumber',
    params: []
  };

  axios.post(url, payload)
    .then(response => {
      console.log('Latest Block:', response.data.result);
    })
    .catch(error => {
      console.error(error);
    });
  ```
</CodeGroup>

Replace `your-api-key` with your actual Alchemy API key from the [Alchemy Dashboard](https://dashboard.alchemy.com/signup).

### 4. Run your script

Run your script to make a request to the Jovay network:

<CodeGroup>
  ```shell shell
  node index.js
  ```
</CodeGroup>

You should see the latest block number from Jovay in your console:

<CodeGroup>
  ```shell shell
  Latest Block: 0x...
  ```
</CodeGroup>
