EOS.IO API library for Go

GoDoc

This library provides simple access to data structures (binary packing and JSON interface) and API calls to an EOS.IO RPC server, running remotely or locally. It provides wallet functionalities (KeyBag), or can sign transaction through the keosd wallet. It also knows about the P2P protocol on port 9876.

As of before the June launch, this library is pretty much in flux. Don't expect stability, as we're moving alongside the main eosio codebase, which changes very fast.

This library is the basis for the eos-bios launch orchestrator tool at https://github.com/tokenbankteam/eos-bios

Basic usage

api := eos.New("http://testnet1.eos.io")

infoResp, _ := api.GetInfo()
accountResp, _ := api.GetAccount("initn")
fmt.Println("Permission for initn:", accountResp.Permissions[0].RequiredAuth.Keys)

eosio.system and eosio.token contract Actions are respectively in:

Example
