# Get Token Metadata

If you want to automatically get the metadata of some ERC20 tokens, definitely check out Chainbase API [Get token metadata](/api-reference/web3-api/token/token-metadata/get-token-metadata). You can easily retrieve the metadata for any ERC20 token with its contract address by using Chainbase API.

## Overview - Tools you need to work with Chainbase

1. A free account at [Chainbase](https://www.chainbase.com) with an API key.
2. An IDE. Our examples are shown in JavaScript, you can use [VS Code](https://code.visualstudio.com/) as your IDE for example.
3. A contract address of an ERC20 token as your input.

## Step 1: Set up a free account at Chainbase

To better leverage the ability that Chainbase provides, you can register [here](http://www.chainbase.com/register) for a free account and access to different APIs and data cloud.

After logging into Chainbase, visit the [dashboard](https://console.chainbase.com/) to get an overview. Create a new project in the console and get an API key.

## Step 2: Write script using Chainbase API

1. Using `fetch` in JavaScript.

```jsx theme={null}
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
contract_addr = '0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0'; // Take Matic Token's contract address as an example.

fetch(`https://api.chainbase.online/v1/token/metadata?chain_id=${network_id}&contract_address=${contract_addr}`, {
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
}).then(response => response.json())
    .then(data => console.log(data.data))
    .catch(error => console.error(error));
```

2. Using `axios` in JavaScript. You need to install `axios` using `npm install axios --save` in the terminal first.

```jsx theme={null}
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
contract_addr = '0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0'; // Take Matic Token's contract address as an example.

const axios = require('axios');
const options = {
    url: `https://api.chainbase.online/v1/token/metadata?chain_id=${network_id}&contract_address=${contract_addr}`,
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
};
axios(options)
    .then(response => console.log(response.data.data))
    .catch(error => console.log(error));
```

## Step 3: Print metadata of an ERC20 token

Chainbase API [Get token metadata](/api-reference/web3-api/token/token-metadata/get-token-metadata) takes the chain id and token contract address as parameters, and returns the metadata of the ERC20 token.

To get data printed, run command `node <filename>.js` in the terminal. In this case, the data returned looks as follows.

```jsx theme={null}
{
	"contract_address": "0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0",
	"name": "Matic Token",
	"symbol": "MATIC",
	"decimals": 18,
	"total_supply": "0x204fce5e3e25026110000000"
}
```
