+Horizon provides an HTTP API to data in the Stellar network. It ingests and re-serves the data produced by the Stellar network in a form that is easier to consume by the average application relative to the performance-oriented data representations used by Stellar Core. This API serves the bridge between apps and [Stellar Core](/docs/run-core-node). Projects like wallets, decentralized exchanges, and asset issuers use Horizon to submit transactions, query an account balance, or stream events like transactions to an account.

+Horizon can be accessed via cURL, a browser, or one of the [Stellar SDKs](/docs/tools/sdks). To reduce the complexity of your project, we recommend you use an SDK instead of making direct API calls.
 
 This guide describes how to administer a production Horizon instance (refer to the [Developers' Blog](https://www.stellar.org/developers-blog/a-new-sun-on-the-horizon) for some background on the performance and architectural improvements of this major version bump). For information about developing on the Horizon codebase, check out the [Development Guide](https://github.com/stellar/go/blob/master/services/horizon/internal/docs/GUIDE_FOR_DEVELOPERS.md).
