# Aptos (APT)

Aptos Network API Reference for seamless interaction with APT nodes, enabling fast, secure, and scalable transactions on a next-generation Layer 1 blockchain.

## Overview of Aptos Network Methods

Aptos is a Layer 1 blockchain built with the [Move programming language](https://move-book.com/), designed to deliver a fast, secure, scalable, and upgradeable ecosystem. With its modular architecture, Aptos enables frequent upgrades, rapid adoption of new technologies, and strong support for emerging use cases. The Aptos API provides developers with the ability to interact with the blockchain seamlessly and possibly. You can do the following with the Aptos API:

1. Query real-time blockchain data
2. Manage and monitor accounts and balances
3. Interact with smart contracts
4. Submit and track transactions
5. Monitor network activity in real-time

Each method will provide you with the following:

1. Clear description of functionality and use cases
2. Required input parameters
3. Sample requests and responses
4. Supported network
5. Code example
6. Integration

> Note: This API is compatible only with Aptos Mainnet.

## Quickstart

In this section, you will learn how to make your first call with either:

* Axios
* Python

### Quickstart with Axios

Before you begin, you must have already installed `npm` or `yarn` on your local machine. If not, check out [npm](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm) or [yarn](https://classic.yarnpkg.com/lang/en/docs/install).

1. Set up your project using this command:

   For npm:

   ```bash
   mkdir aptos-api-quickstart
   cd aptos-api-quickstart
   npm init --yes
   ```

Or yarn:

```bash
mkdir aptos-api-quickstart
cd aptos-api-quickstart
yarn init --yes
```

This creates a project directory named `aptos-api-quickstart` and initialises a Node.js project within it.

2. Install Axios using this command:\
   Using npm:

   ```bash
   npm install axios
   ```

   Using yarn:

   ```bash
   yarn add axios
   ```
3. Create a new file and name it `index.js`. This is where you will make your first call.
4. Set ES module `"type": "module"` in your `package.json`.
5. Add the following code to the file (`index.js`):

   ```js
   import axios from 'axios'

   let account = {
     method: 'get',
     url: 'https://shared.eu-central-1.getblock.io/<ACCESS_TOKEN>/v1/accounts/0xbf9239be9eb7e7a3d8e4c1f36083464fd47e6bd1f82a43b7c0f7ee958705a52f',
   };
    
   axios.request(account)
   .then((response) => {
     console.log(JSON.stringify(response.data));
   })
   .catch((error) => {
     console.log(error);
   });
   ```

   > Replace `<ACCESS_TOKEN>` with your actual access token from GetBlock.
6. Run the script:

   ```bash
   node index.js
   ```

   The sequence number and authentication key log in your console like this:

   ```json
   {
     "Sequence_number": "219241",
     "Authentication_key": "0xbf9239be9eb7e7a3d8e4c1f36083464fd47e6bd1f82a43b7c0f7ee958705a52f"
   }
   ```

### Quickstart with Python and Requests

Before you begin, you must have installed Python and Pip on your local machine.

1. Set up your project using this command:

   ```bash
   mkdir aptos-api-quickstart
   cd aptos-api-quickstart
   ```
2. Set up a virtual environment to isolate dependencies:

   ```bash
   python -m venv venv
   source venv/bin/activate  
   # On Windows, use venv\Scripts\activate
   ```
3. Install the requests library:

   ```bash
   pip install requests
   ```
4. Create a new file called [`main.py`](http://main.py) and insert the following code:

   ```python
   import requests

   url = "https://shared.eu-central-1.getblock.io/<ACCESS_TOKEN>/v1/accounts/0xbf9239be9eb7e7a3d8e4c1f36083464fd47e6bd1f82a43b7c0f7ee958705a52f"

   response = requests.get(url)

   print(response.text)
   ```

   > Replace `<ACCESS_TOKEN>` with your actual access token from GetBlock.
5. Run the script:

   ```bash
   python main.py
   ```
