 Horizon is the [client facing API](/docs) server for the Stellar ecosystem.  It acts as the interface between stellar-core and applications that want to access the Stellar network. It allows you to submit transactions to the network, check the status of accounts, subscribe to event streams, etc. See [an overview of the Stellar ecosystem](https://www.stellar.org/developers/learn/) for more details.
