# API

> Public API endpoints and client libraries for HyperPaxeer.

# API

The following API's are recommended for development purposes. For maximum control and reliability it's recommended to run your own node.

## Networks

Quickly connect your app or client to HyperPaxeer mainnet and public testnets. Head over to [Networks](./api/networks) to find a list of publicly available endpoints that you can use to connect to the HyperPaxeer

## Clients

The HyperPaxeer supports different clients in order to support Cosmos and Ethereum transactions and queries. You can use Swagger as a REST interface for state queries and transactions:
