DeCommas API​

DeCommas API is a speedy, scalable and cost-effective web3 API. It puts indexed blockchain available data in arms reach, making development of web3 applications such as Portfolio Trackers, Wallets, Web3 search bars and Activity feeds a breeze. DeCommas API contains:

  • Datalayer & Datalayer API: Scalable, speedy and cost-efficient indexed Blockchain, NFT and Protocol data accessible through a developer friendly API.
  • Price Service API: provides a comprehensive overview of ERC-20 price calculations using on-chain data from multiple decentralized exchange pools.

Using the DeCommas API, you’ll get access to a develop toolbox that’s:

  • Blazing fast - Accessing indexed blockchain data through the Datalayer API yields response times of under 300ms per request.
  • Free to use in many scenarios - Just getting started or pushing a smaller feature? DeCommas API is, in many cases, completely free to use!
  • Cost-efficient at scale - Highly competitive prices with the potential to decrease infrastructure cost by up to 40-80% (depending on the project's needs).
  • Developer friendly - All of this is accessible through easy to use, flexible and well documented APIs and an SDK.

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!
