## What is Humanity?
Humanity Protocol is a zkEVM Layer-2 for decentralized identity that uses palm-biometric Proof-of-Humanity and zero-knowledge proofs to issue privacy-preserving, Sybil-resistant credentials.

## How do I get started with Humanity?
Check out our [Humanity API Quickstart guide](/docs/reference/humanity-api-quickstart) to get started building on Humanity.

## What is the Humanity API?

## What is a Humanity API key?
When you access the Humanity 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 Humanity?
Common Ethereum libraries like [ethers.js](https://docs.ethers.org/v5/) should be compatible with Humanity, given its EVM nature.
