# What Is Horizon?

Horizon is the client-facing API server for the Stellar ecosystem. It acts as the interface between stellar-core and applications that want to access the Stellar network. Horizon allows you to submit transactions to the network, check account status, subscribe to event streams, and more.

## Develop, Discover, Distribute

The Stellar Horizon API is a rich API with multiple supported SDKs available from Stellar. You can incorporate them into your application and connect directly to the network using languages ranging from C# to Scala. You can make simple REST calls with curl or an API client like Postman.
