horizonclient

horizonclient is a Stellar Go SDK package that provides client access to a horizon server. It supports all endpoints exposed by the horizon API.

This project is maintained by the Stellar Development Foundation.

Getting Started

This library is aimed at developers building Go applications that interact with the Stellar network. It allows users to query the network and submit transactions to the network. The recommended transaction builder for Go programmers is txnbuild. Together, these two libraries provide a complete Stellar SDK.

Prerequisites
  • Go (this repository is officially supported on the last two releases of Go)
  • Modules to manage dependencies
Installing
  • go get github.com/stellar/go/clients/horizonclient
Usage
    ...
    import hClient "github.com/stellar/go/clients/horizonclient"
    ...

    // Use the default pubnet client
    client := hClient.DefaultPublicNetClient

    // Create an account request
    accountRequest := hClient.AccountRequest{AccountID: "GCLWGQPMKXQSPF776IU33AH4PZNOOWNAWGGKVTBQMIC5IMKUNP3E6NVU"}

    // Load the account detail from the network
    account, err := client.AccountDetail(accountRequest)
    if err != nil {
        fmt.Println(err)
        return
    }
    // Account contains information about the stellar account
    fmt.Print(account)

For more examples, refer to the documentation.

Documentation

Overview

Package horizonclient provides client access to a Horizon server, allowing an application to post transactions and look up ledger information.

This library provides an interface to the Stellar Horizon service. It supports the building of Go applications on top of the Stellar network (https://www.stellar.org/). Transactions may be constructed using the sister package to this one, txnbuild (https://github.com/stellar/go/tree/master/txnbuild), and then submitted with this client to any Horizon instance for processing onto the ledger. Together, these two libraries provide a complete Stellar SDK.

For more information and further examples, see https://github.com/stellar/go/blob/master/docs/reference/readme.md
