## What is DATA Network?
DATA Network is a purpose-built EVM-compatible blockchain that enables fast, transparent, and programmable management, licensing, and monetization of intellectual property onchain.

## What is the DATA Network API?

The DATA Network API lets you interface with the DATA Network mainnet and testnet nodes. You can execute transactions, query onchain data, and interact with the DATA Network using the JSON-RPC standard.

## How can I get started using the DATA Network API?

Explained in [DATA Network API Quickstart](/docs/reference/data-network-api-quickstart)

## Is DATA Network EVM compatible?

Yes. DATA Network supports any Ethereum Virtual Machine (EVM) codebase. You can deploy and migrate assets and users from Ethereum L1 and other interoperable chains to DATA Network.

## What API does DATA Network use?

DATA Network uses the JSON-RPC API standard. This API enables blockchain interactions on the DATA Network, letting you read block/transaction data, query chain information, execute smart contracts, and store data onchain.

## What is a DATA Network API key?

When accessing the DATA Network via a node provider like Alchemy, you use an API key to send transactions and retrieve data from the network.

For the best development experience, we recommend that you [sign up for a free API key](https://dashboard.alchemy.com/signup).

## Which libraries support DATA Network?

Common Ethereum libraries like [ethers.js](https://docs.ethers.org/v5/) and [web3.js](https://web3js.readthedocs.io/en/v1.8.2/) should be compatible with DATA Network, given its EVM nature.

## What programming languages work with DATA Network?

Languages that work with Ethereum, such as JavaScript, Solidity, TypeScript, and Shell, are also compatible with DATA Network. Solidity remains the primary choice for smart contract development, while JavaScript is ideal for offchain interactions.

## What does DATA Network use for gas?

The native currency for the DATA Network blockchain is the DATA token (ticker: DATA), which is used for transaction fees (gas), staking, governance, and securing the network.

## What methods does Alchemy support for the DATA Network API?

You can find the list of all the methods Alchemy supports for the DATA Network API on the [DATA Network API Endpoints](/docs/chains#data-network-apis) page.
