Setting up DeCommas API in your environment

You can set up the DeCommas API in your environment using either of these two methods: one is via a raw HTTPS request, and the other is using a special toolkit if you’re into JavaScript.

If you choose the first option, the call will appear as follows:

https://datalayer.decommas.net/datalayer/api/v1/tokens/{address}?api-key={YOUR-API-KEY}

But if you’re more of a JavaScript whiz, we’ve got a kit for you called the DeCommas SDK. You can grab it from here: https://github.com/DeCommas/decommas-sdk.

Here’s how to start: Put the DeCommas API inside your Javascript environment by typing:

npm install @decommas/sdk

Once that’s done, just copy and paste the following code:

import { Decommas } from '@decommas/sdk';
const decommas = new Decommas();
const getVitalikERC20Balances = async () => {
const address = '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045'; // any address
const tokens = await decommas.address.getTokens({ address });
console.log(tokens);
};

Now you’re all set to make full use of the DeCommas API!
